Thanks for your reply, Wired1.

I was hoping to be able to put a selectable image in profile fields and have it show up on the dropdown list. So that (for example) if somebody wanted to show that they took part in an event, they'd have the option of checking off that information in their profile and then having the image/icon represent this.
Kind of how people have the option of showing their AIM name, which is represented by an icon.
(Hope that made sense.)
