GIFs are limited only to 256 colors per image, so if you use one image with many colors ("real" stuff, like that one of Superman drinking, tends to use small amounts of a lot of different colors) that doesn't share too many with the other image, then your software will have to cut the colors down to 256 as best it can when actually saving the final GIF.
Man, now I feel like I should try and put your pictures through that Vischeck tool so I can see how it looks for you.
