album directive

- -Each page containing an `album` directive is treated as a photo album. - -Every image attached to an album or its subpages is considered to be part of -the album. A "viewer" page, with the wiki's default page extension, will be -generated in the [[transient underlay|todo/transient_pages]] to display the -image, if there isn't already a page of the same name as the image: for -instance, if `debconf` is an album and `debconf/tuesday/p100.jpg` exists, -then `debconf/tuesday/p100.mdwn` might be created. +Updated, June 2014: integrated changes from [[KathrynAndersen]], +Lukas Lipavsky and kjs -There's currently a hard-coded list of extensions that are treated as images: -`png`, `gif`, `jpg`, `jpeg` or `mov` files.
