Re: Lists of Picture Albums - confused in 3.0
It's easy to put thumbnail images on a wiki page that link to larger images in a gallery, if that's what you mean. It's also be possible to use wiki pages themselves as the galleries if clicking a thumbnail opens a shadowbox popup with the full-size image. (This is quite a different look, though - see http://zukakakina.com/Shadowbox_gallery.) I'm not sure if I'm answering your question, though, so please add more details if you like.
The file galleries are planned to take over the function of the current image galleries, but there will be an easy migration path for transferring images when that happens. The file galleries will have more image-centric functions by then.
