Is there a problem having my forum visitors upload their images to my wordpress media library, or should I require them to host the images elsewhere? How are other people doing this? Thanks!

As long as you use quality plugins for image upload for bbPress like this one you should be fine.

hosting images elsewhere should help on server disk space though, well unless you have a CDN.
