Subject: Allow using regular images in galleries

Galleries previously required images to be placed in /images/large/..
and /images/thumb/.., but this was a chore if there was only a single
average-quality version of the image to display. The path /images/..
is now used as a fallback if these more specialised paths do not exist.
