Well that would produce one long load time at the start as oppose to many short ones, that would be preferable except that it would cost a huge amount of memory to hold that many backgrounds at once. They are 600X480 and there are around 100 of them. thats 64000 pixels by 480 pixels. I'm trying to keep it down to 32 megs minimum system requirements I doubt 32 megs could hold that much graphical information at once.
