Hmm, I'm unsure how to enable 'safe for web' in the program I use, I think my brother has photoshop, I'll load them up on his laptop and try that. Also, I already tried exporting them as .tga. EDIT: Ahah, figured it out! It was the skin file after all. The syntax was incorrect (I put a space after the comma, so it was looking for " models" rather than "models"), but it seems Modveiw corrects this, allowing it to be displayed correctly. Changed it and it's working. Thanks anyway guys!
