Examples for the Gallery Plugin
Basic Syntax
A basic gallery can be added by selecting a namespace like this:
{{gallery>:wiki:gallery_syntax}}
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>:wiki:gallery_syntax:hockinghills01.jpg}}
The created gallery can be aligned by using white space (defaults to centered):
{{gallery> :wiki:gallery_syntax}} (right aligned)
{{gallery>namespace:wiki:gallery_syntax }} (left aligned)
{{gallery> :wiki:gallery_syntax }} (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>https://www.flickr.com/services/feeds/photos_public.gne?format=rss2}}
Parameters
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. |
Example
{{gallery>:wiki?*01.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.
Example
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 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:
| Key | Action |
|---|---|
→ | next image |
← | previous image |
ESC | close the image view |
Manipulate EXIF Tags
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:Headlinefor the titleIPTC:Caption-Abstractfor the description below the picture in lightbox-modeIPTC:By-linefor the photographer nameIPTC:CopyrightNoticefor the copyrightIPTC:Keywordsfor keyword list
