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

{{gallery>:namespace}}

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 more sense when combined with the lightbox mode (see below).

{{gallery>:namespace:someimage.jpg}}

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:

{{gallery>http://www.23hq.com/rss/schabloni}}

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

{{gallery>images:vacation?image_*.jpg&80x80&crop&lightbox}}

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.

{{gallery>?crop&lightbox}}

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

This mode will open the clicked picture inside the current browser window without leaving the current page.

You can close the picture view by clicking the X button in the upper right corner. You can move to the next or previous image by using the arrow buttons in the lower bar. You can also use the keyboard shortcuts listed below for navigation and closing. Mobile users can swipe to navigate and use the back button to close the gallery.

The following keys can be used to navigate:

If you want to show a title below the image using the parameter showtitle it may appear that the title shown is not as you expected (e.g. einstein.jpg instead of Albert Einstein).

If you want to adapt the image's subtitle shown in the gallery, you have to manipulate the EXIF Tag called Headline. This can be done with the fullscreen media manager. Alternatives include ExifTool for which even a Windows GUI exists to adapt the EXIF data to your needs. On Windows, the small picture viewer IrfanView can also be used to change only IPTC values.

Note that the EXIF-tags used for display can be changed. See EXIF and IPTC metadata for details. By default, the following tags are used:

• IPTC:Headline for the title
• IPTC:Caption-Abstract for the description below the picture in lightbox-mode
• IPTC:By-line for the photographer name
• IPTC:CopyrightNotice for the copyright
• IPTC:Keywords for keyword list

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

• Use the media manager popup or fullscreen media manager to upload multiple image at once with compatible browsers, otherwise one by one.
• Use the archiveupload plugin to upload multiple images in a Zip file
• 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).

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.

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.

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

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.

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