Ironically, the code to randomize the cornerstone was already built for the home page or any non-game pages (such as the forums), but I didn't implement it because there were only two so far, LOL. If any of you guys want to make a few for your favorite games, the dimensions for them must be:
GIF (transparent -- leave room for the Nintendo AGE logo somewhere)
Width: 200 pixels (must be exactly 200)
Height: 250 pixels (at most, but it can be less)
I may try and finish up a few that I'd started on. I didn't realize anyone cared much for that feature!
