This Syntax Plugin allows you to embed an automatically created image gallery into a page.

для админа


A basic gallery can be added by selecting a namespace like this:


All image files in the selected namespace will be added to the image gallery. Don't forget the «:» in front of the namespace.

Instead of using a whole namespace of images, you can also specify a single image – this makes most sense when combined with the lightbox mode (see below).


The created gallery can be aligned by using white space (defaults to centered):

{{gallery> namespace}} (right aligned)
{{gallery>namespace }} (left aligned)
{{gallery> namespace }} (centered)

Instead of a namespace, you can also give an HTTP(s) URL to any Media RSS or ATOM feed with enclosures (as produced by most photo sharing sites like Flickr). The images will then be pulled from that feed instead:


Note: since the question mark is used to separate the parameters (see next section) the URL can not contain any question mark. To use such a feed URL with the gallery plugin, just use one of the many short URL services like http://bit.ly.

E.g. instead of http://api.flickr.com/services/feeds/photos_public.gne?id=22019303@N00&lang=en-us&format=rss_200 use a shortened URL like http://bit.ly/HurZM.

Additionally, to have thumbnail creation correctly working you need to set fetchsize big enough to get the remote images downloaded.


A number of parameters can be set by appending them with ? character to the namespace or image. Each parameter needs to be separated with a & character. Defaults for all parameters can be set in the config manager. If a parameter is enabled by default it can be disabled in the syntax by prefixing it with the syllable no. E.g. the parameter cache is usually enabled and can be disabled using the keyword nocache. Below is a list of all recognized parameters

Parameter Default Description
<number>x<number> 120x120 Sets the size for thumbnails. Unless the crop option is set, this is a boundary box into which the thumbnail will be fitted, maintaining the correct aspect ratio.
<number>X<number> 800X600 Sets the size for the linked images in direct mode. This is a boundary box into which the image will be fitted, maintaining the correct aspect ratio. Note the uppercase X.
<number> 5 The number images per row in the gallery table. If you specify a 0 no table is used instead all thumbnails are added in a sequence.
=<number> =0 Limits the output to the given number of images. 0 means all.
+<number> +0 Skip the first number of images. Useful with the option above.
~<number> ~0 Add a pagination for the thumbnails displaying the number of given thumbnails per page. 0 disables pagination. Pagination is added through JavaScript - when no JavaScript is available all thumbnails are displayed
cache enabled Usually the output of the created gallery is cached. When the images in your selected namespace change, you have to manually force an update of the gallery page's cache. To disable the cache for the page showing the gallery, set nocache as option.
crop disabled Make thumbnails the exact given thumbnail size big, cropping when needed.
direct disabled Link thumbnails with the bigger sized images not with their detail page
lightbox disabled Show images in a fancy JavaScript modal browsing window, see below for details. Setting this option automatically implies the direct mode
reverse disabled Reverse the order of the displayed images
recursive enabled Find images in the given namespace and all sub namespaces
random disabled Sort images randomly. You might want to use nocache as well
modsort disabled Sort images by file modification date
datesort disabled Sort images by EXIF date
titlesort disabled Sort images by EXIF title
showname disabled Show filename below thumbnails
showtitle disabled Show EXIF title below thumbnails
anything containing a * jpg,gif,png images This can be used to filter the list of files found in the given namespace. * work as simple wildcard symbol.



This displays all images beginning with image_ and ending in .jpg from the namespace images:vacation. Thumbnails are cropped to 80×80 pixels and images will be opened in lightbox mode.



This displays all images in the current namespace using 2 parameters. Parameterlist begins with ? additional ones are concatenated with &.

About the Lightbox mode

This mode will open the clicked picture inside the current browser window without leaving the current page1). You can close the picture view by clicking the little X in the upper right corner or anywhere in the picture. You can move to the next or previous image by using the arrow buttons in the lower corners.

The picture is downsized if necessary to fit into the current browser window. You can enlarge it with the arrow button in the top corner.

The following keys can be used to navigate:

Key Action
or n next image
or p previous image
x or c or ESC close the image view

Note: The feature does not use Version 2 of the Lightbox script because of its heavy and DokuWiki-incompatible dependencies.

Known Limitations and Caveats

Uploading Images

Uploading images is beyond the scope of this plugin. Do not request any features regarding this.

  • Use the Mediamanager to upload images one by one
  • Use the archiveupload plugin to upload multiple images in a Zip file
  • Use the Flash Uploader to upload multiple files
  • Upload the files manually via FTP to the data/media directory. Keep in mind that image names need to be valid pagenames, all lowercase, no spaces or special chars!


The gallery output is cached by default. When you add pictures later, they may not show up in the gallery: add &purge=true to the end of the URL to clear the cache. See caching for details.

Optionally use the nocache parameter of the plugin (not recommended).

EXIF Data Problems

Problems with accessing EXIF or IPTC data in the images, should be reported as DokuWiki bugs and not for this plugin. All EXIF handling is in DokuWiki core. Currently EXIF Data is expected in UTF-8 encoding. There are some problems fetching the correct date from images, these are fixed in the current development version of DokuWiki.

When the lightbox mode doesn't work and instead images are simply opened in the same window, the JavaScript was not correctly loaded. This is most likely a Browser-Cache issue. Simply follow the steps described for fixing a similar problem with the toolbar. Also make sure you don't have any conflicting plugin installed. You should not install any additional lightbox plugin.

Images are not Resized

There are different reasons why thumbnails are not created:

  • libGD extension is missing ⇒ Install the extension or configure DokuWiki to use imagemagick
  • libGD extension is installed, but the source image size + overhead is larger than memory_limit set in php.ini ⇒ Lower the source image size or increase the memory_limit

MediaRSS feed displays "nothing found"

When no images from your feed are shown, be sure you don't have a question mark in your URL. Use an URL shortener as suggested above. Also be sure your feed URL (before shortening) starts with http:// or https:// and not with feed://. The latter is just a renamed HTTP link - simply rename it back.

External Images are not Resized

As written above, you need to increase the fetchsize config option. Also make sure LibGD or ImageMagick are installed.

This feature is based on the Lightbox and Lightbox Plus scripts with some additions
