Does it have to be under a file specifically named GUI? If so then that's my problem. I knew that the PNGs could be anywhere, I just wanted to really really make sure that every minute thing was in order. Yeah, adding the PNG's all at the same time works as it should. Alphabetized and in order from left to right. There is no distinct problem other than what I mentioned earlier.
Also, really awesome that you have a Final Fantasy Tactics portrait (if that is what I think it is)!
The mod I'm making is actually trying to add skills from one of the later titles, dragoon type dragon breaths.
