What can this extension do?[edit]
This extension allows you to alphabetically browse through the images in your wiki by adding two links "Previous" and "Next" to the content actions menu when viewing a page in the Image namespace.
It also features a group mode which is useful for galleries of images whose names match the pattern Image:[some description][numbering].[extension]
, like for example Image:Flowers 001.jpg to Image:Flowers 199.jpg.
If group mode is enabled, you can only browse within that group of images (i.e. the Previous and Next links are disabled when reaching the first and last image, respectively, of the group).
This extension is based on Extension:Back-and-Forth by Rob Church.
