I don't know how badly this would stretch your limited server space but I've always liked how members on forums could add a pic of their car or themselves under their personal info when they post (where it says post count, b-day, location, etc.)

Some examples are:
www.supraforums.com
www.finklses.com

Avatars, worst idea, evar.
