There is, I believe. The limit changes depending on the hardware, but it does exist. The intro image itself is very large (over 10000 pixels high) because it's just an ordinary sprite animation.
EDIT: The image is 128x13056. Just never got around to doing anything about it, haha - guess this is as good a time as any!
