Are you refering to saving the picture in whatever program I use outside of MED as a 16.7mill bitmap? In that case I'm not sujre what to do, because MED constructs the picture from 10 different textures. When the model loads in MED, that's when the whole skin is wrong.

I try importing another skin in the skin viewer. Even though the skin is a 24-bit bitmap, it gets messed up in MED and MED's skin viewer. I go to Edit->Convert but Convert is faded out.
