Ok, this is what you do,
If you have any editing program, even Paint shop, open your head with paint, then save another copy of the head as head.tga, then go and find Uke's Custom folder, usually located at 'C
Games\Toribash-3.99\custom\uke'. Then drag the 'Head.tga' into uke's custom folder, and replace the existing 'head.tga' in uke's folder, with your 'Head.tga' that you saved. Go in-game and a 512x512 version of your head will be on uke's head, take a few screenshots and post them here.
