Title
userpic randomizer

Short, concise description of the idea
I'd like the functionality to randomly choose a userpic.

Full description of the idea
This was last suggested in Apr 2010, but I wanted to bring it up again because Dreamwidth has this functionality, so it would be easy to bring over here. The basic idea is that one would click a small button or checkbox and the site would choose a random userpic for you (which you could then change, just in case the chosen picture was inappropriate for the situation). I have a Firefox extension installed solely for this purpose, and I'm sure others do too. It would be great if LJ could do it instead.
