Aquí es donde podrás configurar las partes más importantes de tu galería Coppermine. Algunos ajustes tienen un impacto en los archivos que cargas - la modificación de esas opciones después de haber añadido un gran número de archivos en tu galería puede ser una tarea difícil o imponer modificaciones posteriores que te lleven tiempo. Por esta razón es importante que pases tiempo configurando Coppermine en las primeras etapas del desarrollo de tu galería para conseguir esos ajustes exactamente de la manera que deseas, antes de cargar muchas fotos o de abrir la galería para el público en general.
La mayoría de los campos de opciones de configuración tienen una casilla de verificación en el lado derecho que le permite restablecer esa opción al valor predeterminado (o más bien: recomendado). Esta checkbox sólo será visible si el valor es diferente del predeterminado o si no hay un valor por defecto particular (por ejemplo no se propone una dirección de correo del administrador, ya que esto depende exclusivamente de la configuración de tu servidor) y si has habilitado la opción "Mostrar cajas de 'Reestablecer' en la configuración".
Ten en cuenta que la página de configuración no tiene todas las opciones de Coppermine - algunas se asignan por grupo de usuarios, por lo que las encontrarás en el panel de control de grupos.
Introduce el nombre de tu galería en este campo de texto. El nombre que escribas aparecerá como el título de tu página (barra de título del navegador web) y también se muestra en muchas de las plantillas de los temas.
Incluso si lo quitas en tu tema personalizado debes poner un valor, ya que se utilizará en el envío de postales y en todo tipo de correos electrónicos desde tu galería (por ejemplo, durante el registro).
Es obligatorio rellenar este campo adecuadamente.
Ejemplo: la increíble galería de fotos de Timoteo
Escribe una breve descripción de tu galería en este campo de texto. Esta descripción también aparece en algunas de las plantillas de tema justo debajo del nombre de tu galería.
Al igual que el campo de Nombre de la galería, es necesario rellenar la descripción de la galería aunque el tema personalizado no muestre esa etiqueta e incluso si no deseas mostrar esa etiqueta en tu sitio Web: el campo no debe estar vacío y no debe ser el predeterminado.
Todos los correos electrónicos enviados por la galería tendrán como remitente esta dirección de correo electrónico. Debe ser una dirección de correo válida.
Coppermine usará esta dirección en el campo "De:" en los correos electrónicos (por ejemplo, durante el registro de nuevos usuarios). Es obligatorio tener esta dirección de correo electrónico rellena adecuadamente. Si tienes tu propio dominio podría ser una buena idea usar una cuenta de correo electrónico relacionada con él.
Ejemplo: si el nombre de tu dominio es "ejemplo.com", es buena idea crear una dirección de correo galleria@ejemplo.com y usarla en la configuración de Coppermine. ¡Coppermine no crea esa cuenta de correo!
Los usuarios a veces preguntan en el foro de soporte si se puede utilizar otro correo electrónico, por ejemplo, uno de un proveedor gratuíto como Gmail, Hotmail o similar. La respuesta es: no podemos saber si tu servicio de alojamiento web te permitirá hacer esto. Muchos no lo permiten para prevenir el spam. Recuerda para qué se usará esta dirección de correo: el servidor web mandará los correos desde esa cuenta. Si no estás seguro, consulta con tu proveedor de hosting.
Esta es la dirección a la que se dirige un usuario cuando pulsa en el enlace "Ver más imágenes" de las postales. Debe ser la dirección URL de tu instalación de Coppermine seguido por una barra diagonal (sólo la ruta de acceso a la carpeta de Coppermine, por ejemplo, http://tudominio.tld/Coppermine/). No especifiques un archivo específico (por ejemplo, index.php) o una subcarpeta dentro de la galería Coppermine en este campo.
En versiones anteriores de Coppermine este campo se llamaba "Dirección de destino del enlace 'Ver más imágenes' en las postales", pero como esta URL se usa ahora para más cosas se ha cambiado acorde a su nueva función.
This is the URL where a user will be directed when he clicks on the "Home" button in the main menu. Esta es la dirección a la que van los usuarios cuando pulsan en el botón "Inicio" en el menú principal.
Puedes utilizar "/" al ser la raíz de tu dominio, una página por defecto como "index.php" para acceder a la galería, o cualquier otra dirección URL válida. Por defecto es "index.php".
Si se activa, los usuarios de tu sitio web podrán descargar los archivos que previamente hayan guardado en su colección de favoritos. Estos archivos se descargan de la página "Mis favoritos" del usuario en formato zip. Esta opción necesita que la librería zlib esté instalada en el servidor (ejecuta phpinfo para comprobar si existe en el servidor).
Advertencia: la creación de archivos zip es un proceso que consume muchos recursos en el servidor, y puede sobrecargarlo con rapidez. De hecho, se deben tener en cuenta las mismas limitaciones que se aplican a la carga (por ejemplo, el consumo de memoria) al activar esta función de descarga zip. Es muy probable que esta característica no funcione al intentar crear un archivo zip de un gran número de entradas en el meta-álbum "Mis favoritos" del visitante.
Las opciones son no permitir descargar los favoritos como zip o permitirlo completamente. Si decides permitirlo, se puede escoger si deseas incluir un archivo 'leeme' en el archivo zip que explique que el archivo ha sido descargado de tu galería.
La opción predeterminada (y recomendada) es no permitir ("off").
Especifica la diferencia entre la hora local y la zona horaria de tu servidor web. Este valor se utiliza, entre otros sitios, en las postales.
Permite la visualización de los iconos de ayuda en diversas secciones de la página de administración de Coppermine. Cuando está activada asegúrate de que también has subido la carpeta "docs" en la carpeta de Coppermine a tu servidor web.
Si decides poner "Sí: todos", los usuarios validados (registrados y que hayan entrado) también podrán ver los iconos de ayuda en lugares estratégicos, por ejemplo, al crear una galería de usuario.
Como el texto de ayuda se basa en la documentación que viene con Coppermine, no está disponible en todos los idiomas. Si el idioma nativo de tu(s) usuario(s) no se está entre la documentación traducida, es recomendable establecer esta opción a "Si: sólo administrador" para evitar confundirles.
Cuando se activa, aparecerá una lista de todas las palabras clave introducidas en el campo "Palabras clave" de la página "Editar archivos" en la parte inferior de la página de búsqueda, con cada palabra clave como un enlace en el que pulsar. Sólo se recomienda activar esta opción si tienes un número pequeño de palabras clave (por ejemplo, menos de 100) - ofrecerá a tus usuarios algunas ideas sobre lo que podrían estar buscando en la galería (además de la búsqueda normal). Ten en cuenta que activar esta opción para muchas palabras clave (por ejemplo, miles) puede ralentizar considerablemente la página de búsqueda y puede confundir a los usuarios y visitantes nuevos de su sitio.
Para cada imagen o archivo puedes especificar palabras clave que lo caracterizan. Aquí eliges qué carácter separará las palabras clave cuando escribas varias. No elijas uno que vayas a incluir en una palabra clave. Si sólo tendrás palabras clave de una sola palabra puedes elegir un espacio. Pero si deseas que tus palabras clave tengan varias palabras, elige un carácter diferente. La opción más segura es el punto y coma porque rara vez se utiliza en una palabra clave.
El separador de palabras clave por defecto para las instalaciones nuevas de Coppermine 1.5 es el punto y coma. Para las actualizaciones de Coppermine 1.4 o anteriores se mantiene el espacio. Puedes convertir este separador de palabras clave para las que ya tengas creadas antes por otro valor mediante la entrada en la página de Herramientas de administración.
Por ejemplo, si quieres tener la palabra clave "George Washington" como una palabra clave única, selecciona un punto y coma como separador. A continuación, un conjunto adecuado de las palabras clave de una fotografía del Monte Rushmore sería "George Washington;montaña;Dakota del Sur", que tiene 3 palabras clave separadas por punto y coma.
Activa o desactiva los plugins, con un enlace al gestor de plugins. Esta característica permite a los usuarios avanzados crear plug-ins que pueden modificar la manera en que Coppermine se ve y se comporta sin modificar el código interno de la aplicación. Hay muchos plug-ins aportados por los usuarios e interesantes disponibles en el foro de Coppermine. Puedes encontrar más detalles en la sección de plugins de la documentación. Como los plugins se añaden al núcleo de Coppermine, si tienes problemas prueba a desactivar todos los plugins utilizando esta opción para ver si un plugin en particular puede tener la culpa. Si es así, puedes entonces activar todos los plugins aquí, y a continuación instalar o desinstalar los plugins de uno en uno en el gestor de plugins para averiguar cuál de ellos es la fuente del problema.
Cuando añadas ficheros por lotes a la galería
(que habrás subido antes a tu servidor mediante FTP),
tienes la opción de cambiar entre una lista navegable, donde podrás desplazarte a través de la estructura de directorios en la carpeta albums
o mostrar la estructura del directorio completo.
Activa esta opción si tienes una estructura más amplia de directorios y subdirectorios a través de la que deseas navegar
(es necesario que tu navegador sea capaz de mostrar iframes).
Pon esta opción a "No" (desactivado) si deseas usar el interfaz "clásico" de Coppermine que muestra una lista completa de la estructura de una vez.
Si tienes dificultades con una prueba con la otra.
Puedes alternar entre estas opciones también en la página de agregar por lotes.
Cuando añadas ficheros por lotes a la galería (que habrás subido antes a tu servidor mediante FTP), Coppermine puede procesar varias imágenes al mismo tiempo. El proceso es mucho más rápido, y evita timeouts asociados por lo general a las ejecuciones de scripts que se van de tiempo. Este ajuste especifica el número máximo de imágenes que Coppermine debe procesar a la vez. Para obligar a que las imágenes se procesen una por una puedes establecer este valor a 1. Si tienes un servidor potente y dedicado entonces puedes definirlo para que coincida con el número de procesadores disponibles. El valor predeterminado de 2 debería ser un buen equilibrio entre velocidad y uso del procesador.
En las versiones de Coppermine antes de 1.5 esta opción no estaba disponible, y el número de imágenes procesadas al mismo tiempo dependía de los ajustes del servidor y del navegador que no estaban bajo control del administrador de la galería.
Cuando está habilitado las miniaturas de vista previa se muestran en la página de agregar por lotes.
La vista previa de miniaturas es buena para tener idea de qué archivos se van a añadir en realidad a un álbum al procesar por lotes.
Si siempre añades todos los archivos dentro de una carpeta a un álbum, es seguro desactivar esta función, que ayudará a cargar más rápido la página.
Esta característica no ahorra espacio web ni tiene un impacto en la creación de miniaturas - sólo da más información al cargar, eso es todo.
Puedes alternar entre estas opciones también en la página de agregar por lotes.
Al empezar a trabajar con tu galería deberías dejar esta opción activada hasta que estés convencido de que la adición de lotes funciona como se espera. A continuación puedes desactivar esta opción. Si más tarde descubres que algo va mal con la carga vuelve a habilitar esta función.
Esta opción establece la caducidad de los testigos en los formularios (form tokens) en segundos. No establezcas este valor demasiado bajo, ya que podría interrumpir cargas masivas (por defecto es 5 minutos - 900 segundos). También ten en cuenta que podrías tardar algún tiempo introduciendo una gran cantidad de datos (título, descripción, palabras clave) después de que hayas subido varios archivos, y si excedes el tiempo de vida del testigo no podrás enviar el formulario y todos los datos introducidos se pierden. ¡Se aplica en todos los formularios (y algunos enlaces) en Coppermine!
This the the config section where you can set up the language settings. Make sure to read this section carefully before changing anything here.
All language files are stored in the lang directory on your server.
Languages and internationalization (often refered to as i18n) is a complicated and complex thing. You (as Coppermine admin) probably don't want to go into details, so this documentation skips the in-depth issues existing with i18n and just gives you an overview how Coppermine handles languages.
This sets the default language for your gallery.
Next to this selector, you will find a link to the language manager that allows a more granular control over the language files available and how the gallery should use them.
If enabled, Coppermine will try to determine the language of the site visitor based on the language preference settings in the visitor's browser. If the detected language exists as language file for coppermine, that language will be used for the particular visitor. If the language detection doesn't yield a result, the default language set up in Config will be used instead.
Recommended setting is "Yes".
Details on how Coppermine handles languages can be found in the section Languages of the docs
This should normally be set to "Unicode (utf-8)" (or "Default (language file)"). See the explanation in the "language" section of this documentation.
Use this dropdown list to select the default theme for your gallery (Themes are stored in sub-directories of the themes directory ). Click here for more information.
Themes can be selected individually for each user, as the individual selection is being stored in a cookie. That's why you (as admin) can test a particular theme without making it the default for all visitors of your gallery - just add the theme as URL parameter (see Creating your custom theme → Tipps & tricks). The theme dropdown list on the config screen will set the selected theme as default theme for all visitors of your site. Usually, your visitors are not aware of your gallery's capabilities to use individual themes nor do they know what themes are available on your server (unless you have deliberately enabled the theme selector dropdown feature), so the change made by selecting a different theme will have an impact on all your visitors. You need to keep in mind though that the new default theme will not be taken into account on the very next page (i.e. if you have submit the config form), but only on all subsequent page visits (as the cookie setting will apply one page visit later). Additionally, individually-set theme preferences will override the default, so you (as admin) will not see the gallery using your default theme, but the one you selected using URL parameters. Clear your cookie or reset the theme preference (by using the name of a theme that doesn't exist) to use the default theme again.
Determines wether a sidebar for browsers will be available for members of the admin group, registered users group and guest group.
The sidebar is a minimalistic interface to control your coppermine-driven gallery. Think of it as a sort of snap-in for your favorite browser. If you enabled the sidebar, the control structure of your gallery (with all categories/subcategories and albums) will be available in a separate panel in the browser for faster navigation.
It is recommended that you try this option first for the admin only: play with it and decide if it would be a helpful feature for your site's visitors. If yes, enable/promote the sidebar for the registered users and/or guests as well. It's up to you if you want to promote the usage of the sidebar by displaying a link to it in coppermine's menu or if you want to promote it by some other mechanism (e.g. by telling your users about it on a non-coppermine driven page of your website).
The sidebar is helpful for users who return to your page often. It provides an alternative method of browsing your gallery by displaying a tree structure of your categories, subcategories and albums. It is meant for advanced users who understand how their browser works.
The sidebar install screen tries to auto-detect the operating system and browser that the visitor is using and offers the corresponding option to install the sidebar (as those methods differ from browser to browser). Some browsers are capable of appearing as different browsers, which will make the auto-detection routine fail. Subsequently, there is an option on the install screen as well to skip auto-detection and make the visitor select his browser.
Group membership is being determined if a visitor is logged in or not: if he is not logged in, he is a member of the guest group and the corresponding option set up for guests (anonymous) is being taken into account. If the visitor is logged in, he is automatically a member of the registered group.
There are two independant config sections for granular permissions who can access the sidebar:
Members of the admin group can access the sidebar no matter what option you select.
Possible options for each of the above settings:
Make sure to set the sidebar options up so that they make sense: it is not a bright idea to allow guests to access the sidebar, but deny access to registered users; registered users would be "punished" for registering. It is advisable to test the sidebar feature thoroughly before allowing your visitors to access it.
How the sidebar is installed greatly differs from browser to browser. Sadly, the most complicated version is the sidebar for Internet Explorer, which is the most popular browser. In the past, it has been comparatively easy to add anything to IE's favorites and to come up with a "real" sidebar. However, as Microsoft had some bad press for releasing a browser with severe security holes, the options for developers to create a working sidebar that end users can add easily have been reduced deliberately by Microsoft when releasing patches for their browser and operating system. Therefore, you might have issues with the sidebar, depending on which version of Windows and IE you are using.
If you want to edit the text that explains the install of the sidebar, edit the file http://yoursite.tld/your_coppermine_folder/lang/yourlanguage.php with a plain text editor.
Use this if you want to create a custom link that will appear in the menu. What you enter here will be the name of the menu link or button. Leave space blank if you do not have any specific use for it.
This is the URL where the user's browser will be directed to when s/he clicks on the "Custom link name" button in the main menu.
You can use any valid URL.
Leave this blank if you do not have any specific use for it.
When enabled, this option will display icons next to some menu items to allow an easier navigation. The performance penalty should be neglectible. Default (and recommended) option is "on". Available options are:
The menu icons are themeable, so there can be different icon sets with different themes.
When enabled, this will display the bulletin board codes that may be used in description fields to help with the formatting of text, images and links.
Optional relative path to a custom header file. Using this option, you can include non-coppermine code bits to be included into your theme, e.g. an overall navigation that gets included on your whole website. You can only add a relative path (seen from the root path of your coppermine install) - not an absolute one, nor a http include from another website. This option is only meant for experienced users who have some PHP know-how.
For details on the include files, refer to the section Custom header and footer
The custom include files are an answer to the FAQ "How can I include Coppermine into an existing web site?": although the primary answer to the question is "You can't include Coppermine into another page by using the PHP commands include or require at all.". This looks like a contradiction in terms, but you need to see the idea behind this: everybody who has been using includes agrees that they can be an easy method to efficiently maintain a site without having to edit many files to accomplish only a minor change on all or many pages. You just need to figure this out differently: include your overall site's navigation into coppermine instead of trying to integrate coppermine into an existing site (because you can't do that for technical reasons).
Optional relative path to a custom footer file. The same remarks apply as for the custom header include path.
When enabled, another link in the sub_menu will appear named "By Date". When the user clicks on it, the calendar will open in a pop-up and will allow the user to view files uploaded at a certain date.
When enabled, there will be pages that tell the user if his action has been successful or not, with a link to continue to the next page. If disabled, the user will be redirected to the target page immediately without displaying the redirection page first, with the message displaying at the top of the page instead. Recommended (and default) setting is "No", as it then will need less clicks.
Example: if enabled, users will be sent to a page that says "comment added" after they have submit a comment. Only after clicking on continue they will be sent back to the intermediate image display (where they posted their comment in the first place). If this option stays disabled, the user will see a box at the top of the intermediate image screen that just says "comment added" after he submit his comment.
When enabled, there will be section on the upload screen that is meant to make your visitors aware of the fact that they can upload as well using the XP Publishing Wizard. The link will be displayed regardless of a user's permission to upload in the first place, so make sure to only display the promotional link if your users can actually use the publishing wizard in the first place.
The number you type in here becomes the default width of the display tables used on your main page or when you are viewing thumbnails of an album. You can enter the width in pixels or specify it in percentages. The default value is 100%.
Setting this to a ridiculously high value (i.e. above 100% or a pixel value higher than regular desktop resolutions) doesn't make sense and will lead to unexpected results.
The default value is 2. With this value the script will display the current categories plus one level of sub-categories.
This is the number of albums to display on a page. If the current category contains more albums than what is allowed on the page, the album list will be split over multiple pages with tabs at the bottom of each album list table (pagination) that users can click on to advance to the next set of albums in a particular category.
Default (and recommended) setting is "12".
Self-explanatory. The default value is 2.
This sets the maximum size of the thumbnails that are to be displayed for each album. 50 means that the thumbnail will fit inside a square of 50x50 pixels.
If the size you specify there is larger than "Pictures and thumbnails settings/Max width or height of a thumbnail", the thumbnail will be stretched. Aesthetically, it is better to have thumbnails smaller than or equal to the Max width or height settings here.
This option allows you to change the content of the main page displayed by the script.
The default value is catlist/alblist/random,2/lastup,2
You can use the following "codes" to include other items:
Unless you really know what you are doing you should always keep catlist and alblist in "the content of the main page", as they make up the core parts of the index page or any gallery site, for that matter.
The ,2 dictates that cpg should display 2 rows of thumbnails.
Some example configurations:
There might be plugins that add more codes that can be used in this field.
You can not use a code more than once inside this field: a string like breadcrumb/catlist/alblist/breadcrumb will not work as expected and may have undesired side-effects.
Use this setting to choose whether or not to display thumbnails from the first album of the categories listed on the default gallery entry page.
By default, this option is enabled. If your gallery grows and you get a larger number of categories, you might want to disable this option to make the index page look less cluttered.
Enabling this option will have the advantage that your visitors will need less clicks to reach the page that contains the pics they want to see. Drawback of this option is that your index page may look cluttered and will burn more resouces (CPU cycles), so you should disable this if you have issues with resources consumption.
You can dictate that coppermine sort all categories alphabetically (instead of in a custom order) by setting "Sort categories alphabetically" to "Yes". This setting is accessible both in the coppermine config menu and in the category manager. If you enable alphabetical sorting, the up and down arrows that normally let you move categories up and down in the custom sorting list will disappear.
If you use album keywords to display images/files in more than one album, enabling this option will display additional information for the album stats: if an album doesn't only contain "regular" files, but files linked via the "album keyword" option as well, the number of linked files will be displayed separately like this "3 files, last one added on Oct 07, 2004, 3 linked files, 6 files total".
Default value is 4 this means that each row will show 4 thumbnails. There can be no general recommendation on the number of thumbnail columns you should use, as the optimal setting depends on your thumbnail width setting, the theme you use, the width of the main table and especially the display resolution of your site visitor.
Default value is 3.
If an album contains more files than the number that will fit on one thumbnail page ("Number of columns on thumbnail page" x "Number of rows on thumbnail page"), a pagination tab will be displayed that allows the visitor to jump to the next page of thumbnails.
When the thumbnails spread over multiple pages, tabs are displayed at the bottom of the page. This value define how many tabs will be displayed. If the number of thumbnail pages is greater than the number set for "Maximum number of tabs to display", the "neighbouring" tabs will be displayed as well as the first and last tab.
Default is 12, range is between 5 and 25.
When the thumbnails spread over multiple pages, tabs are displayed at the bottom of the page. This setting will display a dropdown list of all pages so that users can access any page even if the page is not listed in the tabs displayed. To customize the display of tabs further, modify your theme's variable $template_tab_display and function theme_create_tabs.
Toggles whether the file caption is displayed below each thumbnail while user is in (regular) thumbnail view.
Toggles whether the number of views is displayed below each thumbnail while user is in thumbnail view.
Toggles the display of the number of comments for below each thumbnail.
Toggles the display of the name of non-admin uploaders below each thumbnail.
Toggles the display of admin uploader names below each thumbnail for users that have the administrators group set as thier default group.
Toggles the display of the file name below each thumbnail.
It's recommended to leave this option disabled, especially if you have no direct control over the file names (because you allow uploads by users). Better use the actual textual content (title and caption) features. If you have long file names that can not be wrapped, the file name displayed may be wider than the thumbnail, so the table cell that wraps the thumbnail and all text that relates to it may get much wider than expected, resulting in a distorted view of the table.
Toggles the display of the rating results below each thumbnail.
Recommended (and default) setting is "off".
When enabled, this option sends the visitor directly from the thumbnail to the full-sized image pop-up, skipping the display of intermediate images.
It is not recommended to enable this option, becauseThis option has been added because a lot of coppermine users have asked for it. However, the dev team does not recommend using it.
This option determines the default order in which thumbnails should be displayed. Your user can override this by selecting a custom sort order from the sort buttons above the albums.
Used to determine how many votes a file must receive before appearing as a "top-rated file.". If a file has received less than "this value" of votes, it will not be displayed in the "top-rated" page. This value must be greater or equal to 1.
Setting this to a high number is only recommended for busy sites with a lot of visitors. Default value is "1". A higher number has the advantage that votes just by one individual won't boost up the relevance of a file to much, reducing potential rating fraud.
The minimum width of the table (in pixels or %) that will be used to display the intermediate picture.
Examples:
Recommended setting is "100%". When setting this to a value that doesn't make sense (over 100% or a silly absolute size in pixels), your gallery pages will look distorted and horizontal scrollbars will appear.
If you decide to use an absolute size in pixels, make sure that the value is equal or greater than "Max width or height of an intermediate picture".
Define whether or not the file information block that appears below the intermediate image should be visible by default (If turned off, users can still view the info block by clicking on the ( i ) button.
Default setting: off. Recommended setting: on.
When enabled, a link will be displayed in the pic info section (that can be toggled by clicking the (i) button) that allows the visitor to download a movie. If the file displayed is not a movie, but another file type (e.g. an image), the download link will not be displayed.
Maximum number of characters that an image description may contain.
Toggles display of a "film strip" showing thumbnails of prior and subsequent files in the album.
Sets the number of thumbnails to display in film strip. The number you can set here is dependent on your thumbnail size and monitor size. If you do not want to inconvenience users with smaller monitors set this value between 3-7.
It's recommended to use an odd number, so the thumbnail that represents the file actually viewed is being displayed in the center of the film strip. Default (and recommended) setting is 5.
This sets the time that each pic is to be displayed (transition interval) when a user is viewing a slideshow (the next pic is being loaded/cached while the current one is being displayed). This setting must be in milliseconds (1 second = 1000 milliseconds).
Remember that setting this to a very low value may not be in the best interest for all of your users, especially those who are on dial-up connections, or if you have large files (kb) that may take longer than the allotted time to display.
When enabled, the hit counter will increase when a visitor views the slideshow as well. When disabled, the hit counter will only be increased if visitors browse your gallery using the regular navigation. This option may have a slight performance impact, don't enable it when your gallery is slow already.
When enabled, you can not only send images as ecards, but flash files as well. This feature has been added because many users requested it. However, it is not recommended at all, simply because most email clients will not display Flash embedded into emails or (even worse) will show messages that may confuse the recipient.
You have to understand that this setting does not determine the ability of users to send ecards in the first place (this is being configured on the groups page instead). Only if a user is allowed to send ecards (i.e. belongs to a group that is allowed to do so), this setting is being taken into account.
When enabled, a transparent gif will be inserted "over" the pics displayed in your gallery (intermediate sized and full-size pics). Subsequently, if a user right-clicks the image and uses the "save as..." context menu of his browser, only the transparent gif will be saved on his PC, but not the actual image he tried to save. This option will reduce the number of users who are capable to steal your images, but it will only fool newbie users. There is no effective method to completely avoid image theft, but the transparent overlay method is much better than any no-right-click script that keeps users from the legitimate use of the right mouse button and subsequently makes them shy away. Please note that the transparent overlay is being added by using the deprecated HTML attribute "background" to avoid the context menu entry "save background image" that would appear if the overlay image was added using standards-compliant CSS methods. Subsequently, your pages will not contain valid, standards-compliant HTML output if this option is enabled.
Recommended (and default) setting for this option is "off".
If you want to use the old rating system instead of the new one, you have to check this option.
This will not allow you to set a custom amount of rating stars as it defaults back to 5
Used to determine on what scale users will be able to vote. The number you set here will set the amount of rating-stars on the thumbnail page.
Remove "bad words" from comments. The "bad words" list is in the language file. NOTE: Not all language files may contain an equivelent for this list.
Toggle the use of smilies in comments.
This setting toggles flood protection for the comments option. When set to YES, a user can post another comment, even though he already posted a previous one. Some users may abuse this setting. The recommended setting is: NO.
This is designed to prevent someone from breaking the flow of your gallery layout by posting lengthy comments without using spaces between words. With this default value, "words" that longer than 38 characters are automatically censored.
Prevent a comment for containing too many "new line" characters (enter key).
Maximum number of characters that a comment may contain.
Toggle if you want to receive an email each time a comment is being posted. Warning: only enable this option on sites with very low user traffic or you may soon find yourself flooded with notification emails.
Changes the sorting order of comments made to a file.
Ascending: latest comment at the bottom, oldest comment at the top
Descending: latest comment at the top, oldest comment at the bottom
Changes the number of comments displayed per page.
If you allowed anonymous comments (permissions set on the groups control panel), this prefix will be used for comments left by unregistered users. This can be helpful in preventing and identifing unregistered users posting as other registered users (or even an admininstrators) when leaving comments. Leave this blank if you do not want a prefix for guest's comments.
By default, comments don't require approval and are visible instantly. To fight the problem of comment spamming, you can require admin approval of comments posted by users. Comments will then not be visible instantly, but only after admin approval on the review comments screen. If you don't allow comments at all, this setting won't apply, so you can leave it as-is.
Options:
Please note:
With this toggle you can determine if the admin will see only the comments that actually need approval on the "Review Comments" page. You can toggle this option in config or on the actual "Review Comments" page - it won't hurt to toggle this setting frequently when reviewing comments.
This option does not have any impact on the visibility of comments, but only on the "Review Comments" page display.
When enabled, the non-admin end user will see a placeholder text saying Someone has posted a comment here. It will be visible after admin approval. instead of the comment. When disabled, the comment that needs approval will be completely invisible for the end user.
This setting is only being taken into account for non-admin users, so you won't notice any difference when being logged in as admin.
When enabled, users are allowed to edit or delete their comments after submitting them.
Note: this setting doesn't determine if users can actually post comments at all (this is instead being determined on the groups page). Instead, it just displays an edit and delete icon next to a comment that turns the comment into an input field when being clicked.
The admin is not affected at all - he can edit any comment no matter what.
To prevent spam comments being posted by bots (automated scripts), this toggle will display an image next to the comment field with some random letters on it. The visitor is required to enter those letters into a textfield to prove that he's actually a human and not just some dumb bot that drops spam. It's recommended to enable Captchas for anonymous comments (guests who are not logged in).
Note: this setting doesn't determine if guests can actually post comments at all (this is instead being determined on the groups page).
Another method to fight comment spam is the option to filter all comments posted using Akismet. To use this feature, you need a valid Akismet API key. To get such a key, you need to sign up (for free) for small/non-profit pages on the Wordpress page to obtain an API key. If you plan to use Akismet on a commercial page, you need to purchase a professional API key on akismet.com/commercial/
After you got your API key by email you can paste it into this config field. You can not make up the API key, nor can you use someone else's API key.
Leaving this field empty will disable the usage of Akismet.
After entering your Akismet API key into the config field, go to the review comments page - at the bottom you will find a little info box that will display the number of comments that Akismet has blocked for you and a lookup field that displays the results of a connection attempt with the Akismet server using your Akismet API.
Please understand that the Coppermine group is not affiliated in any way to Akismet.com nor Wordpress: the Akismet service is provided by a third party. Terms and conditions of Akismet usage may change at a later stage - the Coppermine dev team doesn't have control over this service and can not be held liable in case something goes wrong in relation to Akismet. The Coppermine dev team just provides an interface within the application's code to allow you to process comments through Akismet.
Please do not ask questions how to get an API key on the Coppermine support board: both the Wordpress pages as well as Akismet.com provide documentation how to obtain an API key. Go to those pages to get your API key.
Find more details on the comments page of the documentation, particularly within the Akismet section of that page.
These options will only be taken into account if you have entered a valid Akismet API key into the corresponding config field. It determines what should be done if Akismet rejects a comment as spam? Here's what the options do:
You can specify if only the comments posted by anonymous visitors (guests) should be checked by Akismet or if all comments that get posted will be pumped through the Akismet filtering.
This toggle does not determine the ability of a registered user or guest to post comments in the first place. The overall switch for that purpose resides on Coppermine's groups control panel instead. The config option "Apply Akismet for comments made by" only applies if users or guests have permission to post comments in the first place.
This toggle will only be taken into account if you have entered a valid Akismet API key into the corresponding config field.
Default value is "Everyone", which is the more restrictive setting - it usually doesn't hurt to spam-check the posting of registered users as well, since some spammers take the time to register and then drop their spam comments as registered users if you let them.
The drawback of this option set to "Everyone" is a slightly increased traffic and (depending on the bandwidth of your webserver) a small penalty in the speed of comment processing - after all, the comments are being sent to a third party site first, where that remote server checks the comment and then returns information to your webserver wether a comment should pass or not. If your site is extremely busy or you have limited bandwidth on your webserver, you should set this option to "Guests only" to lighten the load.
When enabled, an explanation will appear at the bottom of the comment section for anonymous users (guests) that explains that they need to log in if they want to post comments. This is meant to promote registration, to explain to your site's visitors that they could interact even more if they registered.
Of course this message will only be displayed if you have disallowed guests to post comments in the first place (you do so on the group control panel). However, this switch does not take into account if there actually is a user group that is actually allowed to post comments at all, i.e. wether you have configured registered users to post comments. If you don't allow registered users to post comments, then don't enable this option.
Settings that determine if the contact-form is available. Make sure that sending emails from Coppermine works in the first place before enabling the contact form.
Toggles wether the link to the contact form will be displayed in the menu and wether guests (visitors of your gallery who are not logged in) can use the contact form.
Possible options:
If disabled, the below options that apply to guests using the contact form will not be taken into account.
When enabled, the visitor (guest) using the contact form will be allowed to enter his name.
Possible options:
When enabled, the visitor (guest) using the contact form will be allowed to enter his email address.
Possible options:
Toggles wether the link to the contact form will be displayed in the menu for registered users and wether your users (visitors of your gallery who are logged in) can use the contact form.
Possible options:
Subject line for the emails generated by the contact form. Will be put in front of the custom subject line the user can enter (if "Display subject field" is enabled).
When enabled, the visitor (guest or registered user) using the contact form will be allowed to enter a subject line.
Possible options:
When enabled, the sender's email address will be used to send the email (if applicable, i.e. if a valid email exists). This is helpful in terms of comfort, as you can use your email app's reply functionality. The drawback may be issues with the emails not being delivered properly, as you can't be sure that the user has entered his actual email address. Additionally, your webserver's mail server may be configured to only allow certain email addresses in the from field. Anti-spam mechanisms may be in place that validate the domain part of the from-field and only accept emails when the domains of the mail server and the from field match. Subsequently, use this option with care and test it througly before making using it "live".
Recommended (fail-safe) setting is "off".
Sets the dimension (width or height or max aspect or exact) on which the maximum pixel size limitation should apply to for the thumbnail.
The options width or height should be pretty self-explanatory: if you specify the value width for the setting "Use dimension", all thumbnails will have exactly the width (in pixels) that you specify in the setting "Max dimension of a thumbnail". Settings all thumbnails to have the same width makes the "grid" of thumbnails on the thumbnails page look very structured, especially when there is little space between the thumbnail rows. The same thing applies if you choose height - all thumbnails will then have the same height, which will look good particularly when looking at a row of thumbnails, e.g. on the film strip display.
Choosing max aspect means that whatever will be the longer side (width for images in landscape format, height for images in portrait format) will have the dimension you specify in "Max dimension of a thumbnail" - the shorter side will be shorter of course, as the aspect ratio that exists for the orginal pic will be preserved as well for the thumbnail.
Only if you choose exact as value for the setting "Use dimension", the value entered into the field "Height of a thumbnail" will be taken into account at all: the thumbnail will then be resized to the fixed dimensions you specify for width and height. If the aspect ratio of the original doesn't match the aspect ratio that results from the width and height settings for thumbnails, the thumbnail will be cropped as well. The main advantage of this setting is that all your thumbnails will have identical dimensions, which leads to a super-clean look of your thumbnails page, with the drawback of the fact that important parts of the content of the original image may not be visible on the thumbnail page because cropping has been applied. Use this option to create square thumbnails (setting width and height for the thumbnail to the same value).
| Option value | Explanation | Correlation | Advantages | Disadvantages |
|---|---|---|---|---|
| width | Thumbnails will have exactly the same width (in pixels) that you specify in the setting "Max dimension of a thumbnail". The height may differ from thumbnail to thumbnail, as the aspect ratio of the original image is preserved for the thumbnail. | Max dimension of a thumbnail | Nice look for thumbnails aligned vertically. Predictable results for themes with fixed width (i.e. where the content defined by the {GALLERY}-token is meant to fit in a table cell or div container with fixed or limited width. | Doesn't align well horizontally. |
| height | Thumbnails will have exactly the same height (in pixels) that you specify in the setting "Max dimension of a thumbnail". The width may differ from thumbnail to thumbnail, as the aspect ratio of the original image is preserved for the thumbnail. | Max dimension of a thumbnail | Nice look for thumbnails aligned horizontally (e.g. the film strip). | Looks silly for extreme landscape resolutions, e.g. stitched panorama images. Doesn't align well vertically. Unpredictable results for fixed-width themes. |
| max aspect | Whatever will be the longer side (width for images in landscape format, height for images in portrait format) will have the dimension you specify in "Max dimension of a thumbnail" - the shorter side will be shorter of course, as the aspect ratio that exists for the orginal pic will be preserved as well for the thumbnail. This is the recommended setting. | Max dimension of a thumbnail | Thumbnails will have similar files sizes. Estetically pleasant if you have a mixture of landscape and portrait images. | Thumbnail rows and columns will not align. Unpredictable results for narrow themes. |
| exact | Thumbnail will be resized to the fixed dimensions you specify for width and height. All thumbnails will have the same dimensions and look identical. If the aspect ratio of the original doesn't match the aspect ratio that results from the width and height settings for thumbnails, the thumbnail will be cropped as well. | Max dimension of a thumbnail and Height of a thumbnail | Clean look of your thumbnails page because thumbnails will align both vertically as well as horizontally. | Parts of the content of the original image may not be visible on the thumbnail page because cropping has been applied, so your thumbnails may not attract the attention of the visitor. |
Sets the maximum allowable size in pixels for the specified dimension of your thumbnails - it depends on what you have set up in "Use dimension" wether the setting from "Max dimension of a thumbnail" will apply to the width or height or the longer side (max aspect).
For details on this setting please refer to the explanations given in "Use dimension".
Only applies if you use "exact" in "Use dimension". This setting is not being taken into account when "Use dimension" has been set to "height".
For details on this setting please refer to the explanations given in "Use dimension".
This prefix is added to the file name of created thumbnails.
These setting mustn't be changed if you already have files in your database. If you do, all reference to your existing files will become invalid.
It's recommended to leave the setting as is (thumb_) if you're not absolutely sure what you're doing.
This feature is deprecated in cpg1.5.x or better and can no longer be configured, since it only lead to end user confusion. If you performed a fresh install or if you have never changed this prefix, the option won't show through. Only for those who have actually changed this option and have a config setting that differs from the default prefix, the text field will show at all. If this is the case for you: you're strongly encouraged to change this back to the default value to avoid possible issues in future versions.
Bottom line: don't be alarmed if this option doesn't show for you - that's OK.
Unsharp masking is an image manipulation technique of increasing the acutance, or apparent sharpness, of photographic images. The "unsharp" of the name derives from the fact that the technique uses a blurred, or "unsharp", positive to create a "mask" of the original image. The unsharped mask is then combined with the negative, creating the illusion that the resulting image is sharper than the original.
With this setting you toggle the creation of thumbnails on with an unsharp mask applied, i.e. you enable thumbnail sharpening. If this option is enabled, you usually get sharper-looking thumbnails. Turn the option off if the exact looks of the original need to be preserved without the improved visual effect that thumb sharpening applies. Default setting (for compatibility reasons) is "off". Recommended setting is "on".
The amount of sharpening that is applied, listed as a percentage, controling the magnitude of each overshoot (how much darker and how much lighter the edge borders become). This can also be thought of as how much contrast is added at the edges. It does not affect the width of the edge rims.
Recommended setting (and default) is 120.
This setting will only be taken into account if thumbnail sharpening is enabled in the first place.
This affects the size of the edges to be enhanced or how wide the edge rims become, so a smaller radius enhances smaller-scale detail. Higher Radius values can cause halos at the edges, a detectable faint light rim around objects. Fine detail needs a smaller Radius. Radius and Amount interact; reducing one allows more of the other.
Default (and recommended) setting is 0.5
This setting will only be taken into account if thumbnail sharpening is enabled in the first place.
Controls the minimum brightness change that will be sharpened or how far apart adjacent tonal values have to be before the filter does anything. This lack of action is important to prevent smooth areas from becoming speckled. The threshold setting can be used to sharpen more pronounced edges, while leaving more subtle edges untouched. Low values should sharpen more because fewer areas are excluded. Higher threshold values exclude areas of lower contrast.
Default (and recommended) setting is 3
This setting will only be taken into account if thumbnail sharpening is enabled in the first place.
The quality used for JPEG compression when the script resizes an image. Values can range from 0 (worst) to 100 (best). By default this value is set to 80. This value can be set to 75 when using ImageMagick.
Do not change this setting unless you really know what you're doing. Other settings for thumbnail and intermediate pic (dimensions) may have a significant and undesireable impact on filesizes and image quality.
By default, whenever you upload a file, the script creates both a thumbnail of the file (file name using "thumb_" as its prefix) and an intermediate version of the file(file name using "normal_" as its prefix). If you set this option to NO, the intermediate file will not be created. This will keep Coppermine from creating intermediate-sized pics during the upload process, displaying the full-sized picture even on the intermediate-display page (resizing the full-sized image on that screen using the width and height attributes of the <img>-tag) to the size that you have specified for "Max width or height of an intermediate picture". Setting this option to "no" will save webspace but may result in increased loading times for the intermediate image display screen.
Sets the dimension (width or height or max aspect or like thumbnail) on which the maximum pixel size limitation should apply to for the intermediate picture.
The options width or height should be pretty self-explanatory: if you specify the value width for the setting "Use dimension", all intermediate pictures will have exactly the width (in pixels) that you specify in the setting "Max width or height of an intermediate picture".
Choosing max aspect means that whatever will be the longer side (width for images in landscape format, height for images in portrait format) will have the dimension you specify in "Max width or height of an intermediate picture" - the shorter side will be shorter of course.
If you choose like thumbnail as value for the setting "Use dimension", the value entered into the thumbnail field "Use dimension" will be taken into account.
The intermediate pictures are those that appears when you click on a thumbnail. The default value is 400, it means that the intermediate picture will be created to fit inside a square of 400x400 pixels. NOTE: Currently, 33% of your users have monitors set at 800 pixels wide, another 33% have their settings at 1024 pixels, the rest have settings less than or greater than these two numbers. Therefore a setting of 600 or less would fit the screens of most users. Keep in mind,however, that setting this size larger than 400 impacts the file size of your intermediate pictures and the time it takes to download and display on slower connections.
If you disable the creation of intermediate images, the value specified for "Max width or height of an intermediate picture" will still have an impact: the full-size image will then be resized using the width and height attributes of the <img>-tag on the intermediate image display pages (displayimage.php), resizing the full-size pic that way to fit on the page.
Any file with a file size larger than this value will be rejected by the coppermine script. Setting this option to a higher value than what is actually supported by your webserver will only result in "funny" webserver error messages in lieu of "regular" coppermine error messages. Therefore, it is recommended that you set this value to a size that is slightly lower or equal to the max file size that your server is set to handle. The actual size your server can handle cannot be determined by Coppermine (or any PHP script) - when in doubt, contact your webhost.
Prior to an FTP upload of files, it is recommended that the admin use their imaging software to resize (individually or by batch processing) larger files to a more practical size. This will facilitate the FTP process and the creation of intermediate pictures and thumbnails.
Limits the height and width dimensions of the pictures that are uploaded. Resizing large pictures requires a lot of memory and consumes CPU resources. As a result, there are usually limitations that have been set by your webserver (host) regarding the maximum uploadable file sizes - you cannot set this value to one that is higher than what is actually supported by your webserver. Contact your webhost/server if you are not sure about your site's file size limitations. (Ideally, users will resize their pictures to a more manageable size prior to attempting any uploads). Determine what you would like the maximum size for a full size pic should be (dpi and dimensions, while keeping in mind the screen size of your users) and use that as a recommended standard for FTP and user HTTP uploads. Inform your users of this recommended size constraints.)
During the upload process, if images are larger than the maximum width or height allowed they will automatically be resized to the maximum allowable size. Users with especially large files should be advised to resize their pictures outside of coppermine before uploading as this process also consumes considerable resources when processed online.
Note: How the image is resized (width/height/max aspect) is set in the admin option "Use dimension (width or height or Max aspect for thumbnail)"
There are three options:
This setting is used to determine the width of a full-size pop-up, as most major browsers mysteriously add some padding to pics opened in a pop-up. It's recommended to leave this set to the default 5 pixels unless you know what you're doing.
This setting is used to determine the height of a full-size pop-up, as most major browsers mysteriously add some padding to pics opened in a pop-up. It's recommended to leave this set to the default 3 pixels unless you know what you're doing.
If set to YES then your gallery can contain albums that are visible only to users that belong to a specified group. This is ideal for creating albums that contain files that you want accessible to only a select group of people. You could also create a userID and password and inform specific users/customers of the ID and password needed to view these files.
If a user is a member of a group that can have its own gallery and this option is turned on then this user will have the permission to hide any of his/her albums from other users.
This option does not determine whether users can have personal galleries at all, nor does it determine who is allowed to upload and who is not (these settings are accessible in the groups manager). You should only set this option to NO if you really know what you're doing (by default, it is set to YES).
Toggles the display of the private album icons to unlogged users.
Set to 'NO', the album is completely hidden from unauthorised users.
Set to 'YES', the album name, description and statistics are shown, but not the thumbnails or files contained within.
It is recommended to enable this option especially if you want to encourage visitors to register (this does of course only make sense if you allow registered users to see albums that guests are not allowed to see).
When the filename of a file that is uploaded contains any one or more of these characters, the characters will be replaced with an underscore.
Don't change this unless you know exactly what you are doing. Default value is $/\:*?"'<>|` &#@
A significant number of webhosts on the Internet run PHP in safe mode. Coppermine runs without any problem in safe mode and with the "open basedir restriction" active, provided safe mode is properly configured. Unfortunately, on many hosts, safe mode is not configured properly.
If you have issues uploading pics, find out if safe_mode is enabled on your webserver by searching for it on your phpinfo page (go to admin tools -> phpinfo). If safe_mode is enabled there, coppermine might be able to workaround the misconfiguration of your server if you enable coppermine's "silly safe mode" option.
What "silly safe mode" does: if you enable this option, Coppermine will not try to create sub-folders for each user, but upload all files into the root of the userpics folder. There might be a slight performance impact for larger galleries, but then you probably won't be running a large gallery on a "crippled" webserver that is not configured properly.
Before playing with the silly safe mode option, make sure that you have set permissions on the albums folder and everything within it as suggested.
Don't change this if uploading works just fine for you. Do not enable the Coppermine setting "silly safe mode" if your webserver is not running in safe mode in the first place.
Enter the allowed image file types that your image library (GD or ImageMagick) is capable of handling to be allowed as uploads and content in your gallery. Restrict the allowed file types to certain types only by entering a slash-separated list of extensions, e.g. jpg/bmp/tif (only possible if you use ImageMagick) or jpg/png (possible both for Image Magick as well as GD).
You have to understand that you can not specify "all image file types that exist", but instead "all image file types that your image library (GD or ImageMagick) supports.
Specify the allowed movie file types to be uploaded. If you want to restrict the allowable file types to certain extensions only, enter a slash-separated list of extensions, e.g. wmv/avi/mov.
Note that being able to display a movie requires that the cpg-user have the necessary codecs properly configured on their computers to display the movie file, e.g. if you allow the file type mov, the user who wishes to view the file will need to have Apple's Quick-Time plug-in installed. Also note that avi is just a container for different codecs - this means that a computer which is capable of playing movie1.avi may not be capable of playing movie2.avi if those files have been encoded with different 'avi' codecs.
File types supported by Coppermine:
asf/asx/mpg/mpeg/wmv/swf/avi/mov
In Coppermine versions prior to cpg1.5.0, the option "ALL" used to be available as well for this field - it has been removed, as it caused users to think that this actually meant "all movie file types that exist".
If set to YES, movies will instantly start playing when loaded (has no affect on flash files, however). Nothing will happen if the user does not have the necessary codecs installed on their computer. This option is browser-dependant, so there is no guarantee that it will work on all platforms.
Specify the allowable audio file types to be uploaded. If you want to restrict the allowed file types to certain extensions only, enter a slash-separated list of extensions, e.g. wav/mp3/wma.
Note that being able to listen to an audio file requires that the cpg-user have the necessary codecs properly configured on their computers to hear these files, e.g. if you allow the file type mp3, users who wish to listen to the file will need to have a media player installed on their computer that can handle mp3 files.
File types supported by Coppermine:
mp3/midi/mid/wma/wav/ogg
In Coppermine versions prior to cpg1.5.0, the option "ALL" used to be available as well for this field - it has been removed, as it caused users to think that this actually meant "all sound file types that exist".
Specify the allowable document file types to be uploaded. If you want to restrict the allowable file types to certain extensions only, enter a slash-separated list of extensions, e.g. txt/pdf.
Note that being able to browse a document file requires the cpg-user to have a compatible software installed and configured properly on their computer that is capable of displaying the type of document in question, e.g. if you allow the file type xls, users who wish to browse the file will need to have an application installed on their computer that can display MS-Excel sheets. Be extremely careful with documents that are known to be vulnerable to virus contamination, embedded or as macros. This is especially true if you plan to allow users the capability of uploading documents without admin approval.
File types supported by Coppermine:

For security reasons coppermine doesn't enable all document types by default. Before adding more file types, make sure that the file types are supported on your webserver.
In Coppermine versions prior to cpg1.5.0, the option "ALL" used to be available as well for this field - it has been removed, as it caused users to think that this actually meant "all document file types that exist".
Set this to the type of image library you have on your server (must be either GD1, GD2 or ImageMagick). GD2 is the recommended setting.
If you are using GD 1.x and the colors of your thumbnails or intermediate image do not display properly, then, chances are, you actually have GD2 on your server - switch this option to GD 2.x
More recent distributions of PHP come pre-packaged with GD - if you're not sure what you have, set this option to GD2. You can also look at your PHP settings by pointing your browser to the phpinfo.php file in your gallery. eg, http://www.yourgallery.com/your_cpg_folder/phpinfo.php. For more information on using PHP click on this link: phpinfo.
If you intend using ImageMagick's convert executable to resize your pictures, you must enter the absolute path to the name of the directory where the convert program is located in this line. Don't forget the trailing "/" to close the path. This path must only indicate the directory where the convert executable is located, it should not point directly to the convert executable itself.
The path you specify here will only be taken into account if you set the Method for resizing images to "ImageMagick". If you specify anything else there, the Path to ImageMagick's "convert" executable will not be taken into account. You need to make sure to specify a valid path with a traling slash no matter what - the config form will complain if you don't.
Also refer to: What's ImageMagick and how can I get it? and How do I enable ImageMagick on my Windows server?.
On Windows, the path that you need to enter into Coppermine's config can look like this for example: c:/ImageMagick/ if the convert executable actually resides at c:/ImageMagick/convert.exe
If your server is running under Windows, use / and not \ to separate components of the path (eg. use C:/ImageMagick/ and not C:\ImageMagick\). This path must not contain any spaces under Windows so that it will not put ImageMagick in the "Program files" directory.
On Posix-compliant server operating systems (i.e. Unix/Linux/BSD-driven systems), the path that you need to enter into Coppermine's config can look like this: /usr/bin/ if the convert executable resides at /usr/bin/convert (mind the fact that executables on Lunix don't have the extension .exe). Another example for the path you need to enter can be /usr/bin/X11/ if the convert executable resides at /usr/bin/X11/convert.
Here you can add options that will be appended to the command line when executing ImageMagick. Read the ImageMagick Convert manual to see what is available.
With this option turned on, the script will read the EXIF data stored by digicams in JPEG files. For cpg1.x to cpg1.2.1, this option will work only if PHP was compiled with the EXIF extension. Coppermine 1.3.0 (or better) comes with built-in EXIF support even if the webserver itself doesn't have EXIF support, as it uses a separate EXIF class.
Since cpg1.4.x there is even an EXIF-manager available that will allow you to determine what exif fields are supposed to be displayed.
With this option turned on, the script will read the IPTC data stored by digicams in picture files.
Please note: IPTC does not support unicode encoding. Therefore, it may collide with coppermine if you use special, non-latin characters in your IPTC tags.
This is the base directory for your "Image Store". The path is relative to the main directory of the script.
You can use ../ in the path to move-up one level in the directory tree.
You can not use an absolute path there ("/var/my_images/" will not work) and the album directory must be visible by your web server.
This setting mustn't be changed if you already have files in your database. If you do so, all references to your existing files will break.
Default value is albums/
Unless you really know what you are doing, do not change this setting.
This is the directory where files uploaded using the web interface (URL/URI) are stored. This directory is a subdirectory of the album directory. It's recommended that you leave this setting as is. Should you decide to change it, keep in mind that the folder must exist within the albums folder and the path should be relative to it.
The same remarks as above apply.
When you upload files by FTP, store them in a subdirectory (folder) of the "album directory" and not inside the "directory for user files".
This setting mustn't be changed if you already have files in your database. If you do, all reference to previously existing files will no longer be valid.
Default value is userpics/
This prefix is added to the file name of created pictures.
These setting mustn't be changed if you already have files in your database. If you do, all reference to your existing files will become invalid.
Default prefix is normal_.
This feature is deprecated in cpg1.5.x or better and can no longer be configured, since it only lead to end user confusion. If you performed a fresh install or if you have never changed this prefix, the option won't show through. Only for those who have actually changed this option and have a config setting that differs from the default prefix, the text field will show at all. If this is the case for you: you're strongly encouraged to change this back to the default value to avoid possible issues in future versions.
If, and only if, during the file upload or batch add process, the installer complains about the directory not having the right permissions, try setting this to 0777 . Failure to do so may prevent you from being able to delete directories created by the script with your FTP client should you ever decide it necessary to uninstall the coppermine script.
Note: setting this option doesn't CHMOD the files or folders that are being uploaded. Instead, the setting is used when coppermine, itself, creates new folders for user uploads (within the userpics directory). If you experienced problems during the initial Coppermine setup related to permissions, this option is not what you have been looking for nor should it be changed (for more information regarding CHMOD, see the permissions section of this document and the FAQ section).
If, and only if, during the file upload or batch add process, the installer complains about the directory not having the right permissions, try setting this to 0666.
Note: setting this option doesn't CHMOD the files or folders that are being uploaded. Instead, the setting is used when coppermine, itself, creates new folders for user uploads (within the userpics directory). If you experienced problems during the initial Coppermine setup related to permissions, this option is not what you have been looking for nor should it be changed (for more information regarding CHMOD, see the permissions section of this document and the FAQ.htm document located in the DOCS folder of this installation package).
Starting with cpg1.5.x Coppermine comes with support for permanently watermarking pictures with the possibility to undo the watermarking. Use watermarking to protect your images against theft.
Details on watermarking can be found on the corresponding article in the docs.
General toggle that determines if watermarking should be enabled or disabled. By default, it is disabled.
Remember as well that watermarking will not only have an impact on the quality and recources consumption (in turns of burning CPU cycles on the server), but as well in the consumption of webspace: when watermarking is enabled, coppermine will keep a safe, unmodified copy of the orginal image (prefixed with "orig_") in the same folder your watermarked file will reside and thus consume additional webspace.
You can use the admin tools to get rid of this copy as well, ,but you have to keep in mind then that there is not turning back in this case: if you delete the unmarked original, you can never go back or apply another watermark.
When enabled, custom thumbnails will be watermarked as well.
If you don't use custom thumbnails, don't worry about this option.
Determines where the watermark is supposed to be displayed on each picture. Possible options are:
Determines which files the watermarking should be applied to. Possible options are:
All three options make sense in different environments: if you want to use watermarking to encourage your users to register, you should apply the watermark to resized image (intermediate images) only and only allow registered users to access the original (full-sized) images. On the other hand, if you only want to make sure that your high-resolution full-size images are not being stolen, apply the watermark to the original only.
Specify the relative path to the watermark file, seen from the root folder of your coppermine-gallery. Default value: images/watermark.png. You can (and are even encouraged) to come up with a watermarking file of your own - only a standard desktop drawing application is needed, e.g. MS Paint.
Coppermine only comes with a sample watermarking file that you should not apply lightheartedly, as it is only meant for testing purposes and to give you an idea how the watermarking file could look like. You have to come up with your custom watermark file and FTP-upload that file to your webserver. It's a good idea to name it accordingly, e.g. "custom_watermark.png" and upload it to the images folder (http://your_domain.tld/your_coppermine_folder/images/). All you then have to do is change the setting for "Which file to use for watermark" to images/custom_watermark.png.
Coming up with a custom watermark can be tricky: it should work well both for dark as well as light backgrounds. You have to find a good compromise: the watermarked files should be still OK to look at, while on the other hand potential image thieves should get discouraged to steal your watermarked images.
Determines the transparency level for the watermark. By setting transparency you can make your image blend nicely into the pictures you upload that get watermarked.
Default is 40
That is the 100% reference point. Resizing of the watermark is linear (0 to disable).
Keep in mind that images might get uploaded by your users (if you allow uploads by others than the admin) that you might not have made up your mind about: the image uploaded may be smaller in resolution. If the dimension of the image uploaded is smaller than the dimension of your watermark file, the watermarking would get cut off and look silly. That's why this option exists: you can specify that images that are smaller than a particular size will have the watermarking applied in a resized manner, making the watermark again fit on the uploaded image. It's a good idea to set this option to the horizontal dimension of your watermarking image.
This option is only available if you have set the method for resizing images to GD2. If you have set it to GD1 or ImageMagick, this setting will not be taken into account at all. Specify the horizontal coordinate of the pixel that should represent the transparent color, seen from the left of the watermarking image.
The transparency setting is particularly usefull if you use a jpeg image as watermarking file or if you don't know how to set transparency up for your watermarking image inside the desktop app where you compose your custom watermark. Your best option (to go out of harms way) will be to use a png watermarking file with transparency - in this case, this setting will not be needed.
This option is only available if you have set the method for resizing images to GD2. If you have set it to GD1 or ImageMagick, this setting will not be taken into account at all. Specify the vertical coordinate of the pixel that should represent the transparent color, seen from the top of the watermarking image.
The transparency setting is particularly usefull if you use a jpeg image as watermarking file or if you don't know how to set transparency up for your watermarking image inside the desktop app where you compose your custom watermark. Your best option (to go out of harms way) will be to use a png watermarking file with transparency - in this case, this setting will not be needed.
Defines whether new users can self-register or not. If you set this to NO, only the admin can create new users and the "register" link won't be displayed in the navigation.
This password should be known by users who want to register. They will be asked for this password on the registration form. User will be able to set his own password while registring. User's password should be different from the global password. To disable global password, leave the field blank.
This option is meant for galleries that are half-private. Example use: if you're going to take pics on a wedding, just tell the guest of the wedding party to visit your page and to use the global password set up here. As a result, visitors who have been guests of that party can actually register, but others who just came to your gallery by accident can't.
Toggles wether users will see the disclaimer on the registration page. You have the option not to display the disclaimer at all, display it as separate page before the actual registration page or inline on the registration page.
This setting only applies if coppermine is not bridged.
To prevent automated registration by bots (automated scripts), this toggle will display an image on the registration page with some random letters on it. The visitor who is trying to register is required to enter those letters into a textfield to prove that he's actually a human and not just some dumb bot.
Note: this setting isn't being taken into account when coppermine is bridged.
If set to YES an email will be sent to the user that will contain a code to activate his account. If set to NO, user accounts become immediately active.
If set to YES an email will be sent to the gallery admin when a new user registers.
Enable admin activation. When set to yes, a gallery administrator must first activate the new registration before the user can log-in and take advantage of any registered user privileges.
By default, it is set to no, so users would activate their own accounts upon registering.
When enabled, each user will have a personal album created during the registration process, even if your permissions for the group new users are in do not allow this (i.e. if you have allowed personal galleries for members of the registered group disabled). Warning: usually, only a small percentage of registered users actually upload files - when this option is enabled, a lot of unneeded user galleries will be created, severely cluttering the database (which has an impact on performance). Don't enable this option if you don't know what it actually does!
This option is disabled when being bridged.
When set to "No", unlogged users (i.e. guests or anonymous users) can not access anything in your gallery except the login screen (and the registration screen, if you allow registrations). Completely disabling anonymous access will probably decrease your site's popularity. Use this option only if you need your gallery to be absolutely private. The recommended setting is to leave anonymous access enabled and use the more specific permissions by groups and albums settings instead.
This option can be set to 4 different levels of access for anonymous users:
Keep in mind that search engine spiders will be treated as non-registered guests as well, so if you restrict the accessibility for guests, search engine spiders will not index whatever you hide from your guests.
Select which type of form users will use to upload files:
There might be other choices you can choose. If so, these come from plugins you have installed. The basic Coppermine options are the two listed above. For assistance on any other upload methods, please check your plugins and their documentation.
You are encouraged to use the advanced upload form unless you have problems with it. This form uses SWFUpload, which has some known issues.
Since it is your users who will run into these problems, you may want to allow your users to choose the upload method themselves. See the configuration setting "Allow users to choose the upload method".
When enabled, users can choose the upload method themselves. This is recommended so that if some users have an issue with their web browsers or operating systems, they can choose another upload method that works better. At the very least, they can use the simple, one file at-a-time, upload method.
Allow or prevent two users from registering with the same email address. Recommended setting is NO. As most internet users today have more than one email address, this option is being considered as deprecated and has been removed in cpg1.5.x for fresh installs. Only if you have upgraded from an older version you should be able to see this option. It's a one-way settimg though: once you disallow identical email addresses for different users, you can not re-enable that option. It's recommended to turn this option off if you have it turned on.
When enabled, the gallery admin receives an email notification of all pics that await for his/her approval (depends on the approval settings in "groups"). The email is sent to the address specified in "General settings".
This option is only recommended for websites with low or medium traffic (where users only upload every now and then).
When enabled, an additional menu item "Memberlist" is displayed in the coppermine main menu if a user is logged in, to let him see a list of all users, with stats on their last visits, uploads and quota usage.
Recommended setting is 'no', especially if you're concerned about your user's privacy.
This option impacts the user's profile page, it determines whether or not the user can change his/her own email address.
Use this option wisely, as the old email address of a user is not preserved after a change: if you allow users to change their email address, abusers may change it to a non-existing email address (e.g. after uploading some pics that go against your gallery's rules) - you would have no chance of tracking this user.
When enabled, users can delete their user accounts. This option has been added in cpg1.5.x because of legal requirements in some countries.
When enabled, both the admin and the uploading user can edit and delete files that were uploaded to a public gallery. Of course the user must have permissions to upload to the public gallery in the first place (see the groups control panel) before this option will have any effect.
When enabled, users will be able to move their albums around from/to categories that the admin has allowed.
When enabled, users will be able to edit their albums even if the admin has locked down the category the album resides in.
When enabled, users will be allowed to assign an album keyword to albums they have control over. This setting doesn't have an impact on the admin - the admin can assign and edit album keywords no matter what. If you allow users to assign album keywords, files from other albums that contain the album keyword set as individual file keyword will show up in their album as linked file.
You can have your users login with their username, email address or let them choose themselves.
Select the option you want in the dropdown.
To make brute force attacks (where a hostile script tries to log into coppermine as admin by running through all possible combinations of username and password automatically) less effective Coppermine temporarily bans the IP address of a possible attacker after a certain amount of failed logins. This way, the brute force attack would need way to long to try all possible combinations.
With this setting you specify the maximum number of failed log-in attempts before the IP address of the user is temporarily banned.
Keep in mind that this setting will definitely have an impact on your legitimate ability to log in as well: if you mis-type your password too often or if someone else has tried to brute-force your admin account, you will be banned temporarily as well. The ban will of course go away after the time set below, but during the ban phase you will be locked out from administration just as well as an attacker would be logged out.
Default and recommended value is 5. Value can range between 1 and 20 (as 0 would mean that zero logins are allowed, which would lock you (as admin) out permanently as well.
This value specifies the duration of the temporary ban (in minutes) after the number of failed log-in attempts specified with Number of failed login attempts until temporary ban.
The warnings posted above for Number of failed login attempts until temporary ban applies here as well: setting this to a value that doesn't make sense will have an impact on legitimate users as well!
Default is 10 minutes. Range is between 0 (which would mean that there will be no temporary ban at all, so use this value to disable the temporary ban feature alltogether) and 9999 minutes (which is roughly less than a week).
When enabled, ban records that have a set expiry date will be deleted as soon as the expiry date is reached. This setting will not have an impact wether the banned user will be able to log in again or not. Instead, this option is meant if you want to preserve records of users who misbehaved in the past and therefore have been banned temporarily. If you do not automatically purge those records, then the ban record will show on the ban users page for the admin, together with an indicator that will show that the ban has expired.
The drawback of turning this option off is the fact that the database table that contains the ban records will fill faster and the ban users page will look more cluttered. Subsequently, the ban lookup for each page will take a little longer. If you have performance issues, turn this option on, as it will purge unneeded records from the ban table.
When set to "yes," this feature will allow users to report on uploaded files or comments to the site admin.
When enabled, an additional icon will appear in the navigation bar that visitors can click on. If they do, they are being sent to a form where they can explain why they want to see a particular file reported to the admin.
There is a number of pre-defined reasons for the reports (like "obscene", "offensive", "off-topic/misplaced", "missing", "error/cannot view") that visitors can choose from and a text field where they can enter additional information.
This setting is dependant on e-cards being enabled. Only users who have permission to send e-cards in the 'groups' settings are able to send reports. The report icon is hidden from those not allowed to do so.
It's advisable to enable this feature on larger, community-driven galleries that don't require admin-approval for uploaded pics, as it gives your community the chance to alert you of potential issues and keep your gallery clean.
As a drawback, the feature can be abused by spammers to send emails to the admin, so it's advisable to only allow reports for registered users.
Determines if your users can rate their own files or not. Recommended setting is "no" to make sure there is no rating war among your users who try to boost their popularity by committing rating fraud.
This option does not determine wether your visitors will be able to rate files at all. "Users can rate their own files" will only apply if rating is enabled in the first place, i.e. if the user belongs to a group that is allowed to rate/vote (you can determine the overall rating permission per group on the groups control panel) and if rating is enabled for the album the file is in (you can toggle the ability to rate on or off on a per-album base - use the controls on the album properties page to accomplish that).
Leave blank if unused. Use Profile 6 for long entries, such as biographies
These fields are displayed within the "user profile" area. They will appear only if you assign a name to the field. As instructed in the heading, use field 6 for long entries, such as biographies, or if you want to include the use of bb code.
You can also use field 6 for avatars. To show an avatar in the profile, it should be entered in bbcode, for example to show 'avatar.gif', which is located in your images folder, use the code [img]http://www.yoursite.com/images/avatar.gif[/img]
Leave blank if unused.
These fields are displayed within the "file information" area. They will appear only if you give them a name.
Default value is something like "cpg15x". Even if you have multiple instances of the script running on the same server you can keep the default value.
This has to be a valid cookie name (no special chars, particularly no dots!) - this setting should best be left alone unless you really know your way around. After all, the cookie name doesn't matter and doesn't mean anything to the end user anyway. Let me repeat: there are many users who blindly change the cookie name to something that just doesn't make sense at all and then complain on the coppermine support board that things are not working as expected. Do not use special chars in the cookie name! In fact, don't change it at all unless you must.
Default value is "/". Don't change this unless you know what you are doing. This may prevent you from logging in.
If you have broken your gallery by modifying this value, use phpMyAdmin to edit the xxxx_config table in your database and restore the default value.
When using bbs integration into Coppermine (aka bridging), make sure to use different cookie names for coppermine and your bridging app! The paths in both applications have to be set so coppermine is able to read both. Usually the default value "/" should be set as path both for coppermine install and the BBS app you bridge with.
Usually nothing has to be changed here; leave all fields blank when not sure. Only if you run into problems (e.g. if ecards, registration info or notifications don't get sent) you should change these settings. Coppermine itself doesn't come with an engine to send mails, it relies on a webserver being able to do so (using the built-in mechanisms of PHP). If you're not sure what to enter, ask your webhost for support.
Using SMTP to send emails: by default the script uses the PHP built-in mail function to send emails. In some cases, the PHP built-in function can't be used.
If, in order to send emails with PHP, you are required to supply a hostname, a username and a password, you will need to edit the CONFIG menu section "Email settings" and insert the correct values there. If you don't need a username and password to connect to your SMTP server, just leave these lines blank. If you don't know what settings to enter, you will need to check with your webhost.
The hostname of the SMTP server
If you leave this blank, sendmail (or a surrogate) will be used to send emails from your server. Sendmail exists on most Unix/Linux webservers. If you specify a SMTP hostname, Coppermine will try to send emails using SMTP (this usually is needed on Windows webservers).
To specify a non-default port number enter it after the hostname with a colon, for example yourdomain.com:26 to use port 26. To use SSL or TLS add a prefix to the hostname, for example ssl://yourdomain.com to use an SSL encrypted connection. You must have OpenSSL support enabled in PHP and the SMTP server must support SSL connections for this to work. You can use both an SSL prefix and a port number if neccessary. To use gmail's SMTP server you would use ssl://smtp.gmail.com:465
The username needed to authenticate on the SMTP server (this is not your coppermine admin username).
The password that goes with above mentioned username (not identical to your coppermine admin password).
Like all logs (that record data that would get dropped if logging was disabled), the logging features of Coppermine will have a slight performance impact as well as an impact on webspace and database usage. You should make up your mind if you actually will need the logs before enabling the feature. A log is only helpful if the admin actually looks into it.
Set, what kind of logging you want to enable. This feature records all changes that are done in coppermine's database, which is especially helpful if you're trying to debug or if there are various admins on a gallery.
All log files are written in english
You have to understand that this option does not toggle the recording of what your site visitors do. Instead, you log particularly what admins do.
When enabled, all ecards that are being sent are as well written into the database, where the coppermine admin can view them. Before switching this option on, make sure that logging is legal in your country. It is also advisable to notify your users that all ecards are being logged (preferrably on the registration screen).
Enabling this option records:
of the voter.
As the statistics are being kept per file, the link to the stats can be accessed on the individual file's page (displayimage.php) by clicking the link in the file info section to open the stats pop-up. Alternatively, you can access the overall stats for your entire gallery by clicking on the admin menu item "Overall stats", which will of course only show if you have enabled stat recording in the first place.
This feature can be very usefull to find out about voting/rating fraud, so if voting is an important part of your gallery (i.e. if you're running a community-driven gallery where users can gain something for voting or for obtaining good votes) it's advisable to turn this feature on.
Enabling this option records:
of the visitor.
As the statistics are being kept per file, the link to the stats can be accessed on the individual file's page (displayimage.php) by clicking the link in the file info section to open the stats pop-up. Alternatively, you can access the overall stats for your entire gallery by clicking on the admin menu item "Overall stats", which will of course only show if you have enabled stat recording in the first place.
Do not enable this option if you don't need it! If you enable it, frequently check the size of the stats table in the database (using a third party tool like phpMyAdmin) and the impact of the stats recording on the overall performance. Make sure that you understand the performance impact that enabling this option has. If you need really detailed stats, you might consider implementing a third-party tool like Google Analytics, which will in turn be less resources-consuming for your server.
Turning this option off ("No") will keep the text X files in X albums and X categories with X comments viewed X times from appearing on the index pages (category and album views). Disabling this option will slightly improve performance, as the stats query that builds those numbers doesn't have to be performed. Default value is "Yes", which means that the feature is enabled ("On").
Turning this option off ("No") will disable counting of file views. This does not affect the display of the view counter. Disabling this option will slightly improve performance. Default value is "Yes", which means that the feature is enabled ("On").
Turning this option off ("No") will disable counting of album views. This does not affect the display of the view counter. Disabling this option will slightly improve performance. Default value is "Yes", which means that the feature is enabled ("On").
Turning this option on ("Yes") will enable counting of admin views. This does not affect the display of the view counter. Default value is "No", which means that the feature is disabled ("Off").
The settings here will not give you additional features to enhance your gallery. Instead, they are meant for maintenance purposes only, so only enable the options here if you actually need them.
Coppermine will show error messages which are normally suppressed. This is helpful in troubleshooting problems with your gallery or when asking for help on the CPG Support Forums. Turn this feature off if you don't experience problems.
Turn it on (option "Everyone") if you are requesting help on the coppermine support board, so the supporters can have a look at the debug output as well. Choose the option "Admin only" when troubleshooting on your own - debug output will be only visible when you're logged in as admin, regular users or guests won't see the debug output.
Do not post debug_output on the coppermine support board unless a supporter explicitely asks for it!
The debug_output will appear at the bottom of your gallery's output, together with a link to your phpinfo output for the admin. By default, the debug_output textarea will be displayed collapsed to make sure that it doesn't interfere with the width of your page. To actually see the debug_output, click on the show/hide toggle that will expand or collapse the debug_output field.
The debug_output contains the following sub-sections:
May be helpful to troubleshoot problems with your coppermine install - only recommended if you know a little PHP and you can understand the additional error messages this option shows. Notices being displayed don't actually mean that there is something wrong with your gallery. This option only applies if debug mode is enabled.
If you enable this option, you will see notices all over your coppermine-driven pages. This does not mean that there is actually something wrong with your install. As suggested above: leave notices_display off if it doesn't mean anything to you. In fact this can be considered a dev-only feature that merely exists to help the Coppermine dev team members to troublehsoot particular issues when coding.
The supporters on the Coppermine support board are not very keen to see posting where people complain that "funny output" resides on their gallery when it later turns out that the output they don't understand just is notices output, so if you have been sent here directly from a posting made by a supporter you should feel a little bit guilty for not reading first.
If you have to do maintenance work on your gallery, switch it to offline mode. Only members of the admin group will be able to log in, all other users will only see "Gallery is offline". Remember to switch this option off once your maintenance work is done.
Starting with cpg1.5.0 there is a feed from coppermine-gallery.net that is being displayed for the gallery admin (and for the gallery-admin only) on each and every coppermine page to alert him of potential security issues and upgrades. You can toggle this option on and off in Coppermine's config (default is "on"). It is recommended to leave it enabled to make sure your coppermine install is always up-to-date.
This is meant as a service for gallery admins; you're of course welcome to disable this option at any time. Coppermine-gallery.net will not collect data from your site (although this would be technically possible to a certain extent). If you're concerned about this option, then disable it or review the code used. We (the Coppermine dev team) are not trying to spy on our users - the feed is only being used to alert you of issues related to coppermine - that's all.
When enabled, there will be reset boxes all over the config screen that show if a particular value differs from default. This will allow you to quickly set the value back to default. This will however eat a lot of resources and will not work in all browsers. Recommended setting is "off", at least if you experience issues with the loading speed of the config screen.
There is a hidden option to reset the entire configuration and restore the factory defaults. You can't access that option using a button in Coppermine's user interface to make sure it isn't being tampered with lightheartedly out of curiosity. To restore the entire coppermine config to factory defaults, you need to go to the config panel and then add the parameter ?restore to the URL.
On that "restore factory defaults" page, you need to tick the confirmation checkbox and submit the form by clicking on the button at the bottom.
