Seconded.  This is one thing that I rarely see in forums, and would ultimately make things easier and less annoying.

Though the problem is, where would the images go?  They'd be uploaded somewhere, and I'd imagine that'd be a strain on the server.

Photo galleries are on the to-do list. They'll support images hosted either locally or remotely, but I'll be placing some sort of limit on the file sizes and number of images per user.
