Gallery Plugin

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 config: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 the EXIF tag Headline as 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.

{{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.
• 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!
• Images previously rotated 90˚ and saved in that orientation no longer appear that way when used in dokuwiki.
