There actually is a tutorial on it. If you go to this link http://www.rpgplanet.com/arcanum/tinker ... portraits1 you can find a collection of portraits and an explanation of how to use them. Here's another source of portraits http://galleriaarcanum.50megs.com/ but it may have the same portraits, I can't remember.
RE thanks, but no thanks. thank you for giving me that info Sinbad! but its too involved for me. I'll do that later when I have most of the mod pretty much done.
