OK, I've just successfully created my first MAT files (waits for applause to die down)... Now what I want to know is this: how do I substitute the image that appears in the menu for one of my own? What I mean is, y'know when you buy a commercial MAT file, it usually has writing on it, or a logo or something. If I wanted to substitute an alternative image rather than use the Poser default, what do I do?
