Topsite, I have an idea. Start up a game of KotOR with the avatar and make sure the resolution is at its highest (1280x1024), I think. Hit the Print-Screen key to take a screenshot and then paste it in Paint, or Photoshop etc. Then crop the image to the avatar and I'm guessing the avvy should be large enough...
(Or just give me a link to the entire screenshot, I'll handle the rest
I would have done it myself, but I uninstalled KotOR1 a long time ago.
