I think this might be a good time (Once Brad is finished with the comic comments) to put all the backgrounds into several different categories, with a second box to the side, like the characters have. I like having lots of backgrounds, but as I'm always drunk, I can never remember which ones are photos and which are drawn. Or really what any of them are most of the time. The list has gotten pretty big. I'm thinking for categories:
photographic
home
abstract
solid color
inside
outside
misc
These are just suggestions, I sort of scanned through the list. I dunno, what do you think?
