It's supposed to be fun anonymous forum when people would use names of politicians and celebrities - using their faces next to the post would make it so much more funny!!!

I have like 200 faces already but can't use them.

They are stored on my website. I know, I don't need that to cure cancer but there's really high demand for that between the members of my forum...
Avatars would have to be not actually Avatars - simply a link to a picture within a catalogue on my website.
So the question should actually be:
Can I add a field somewhere next to the user (guest) name where I could browse for a picture from a predefined catalogue? Maybe it's just a matter of copying the same piece of code that enables choosing the Avatar in the Profile screen.

I suck as a programmer but could try playing around if you anybody gave me a hint....
