Yes, I can allow 17 x 22 maps as this is standard CBT sized maps. However, if you can handle 17 x 22, why not 18 x 24, there's hardly a difference in file size for that. I'd like to stick to a minimum size and not allow every size possible. If you're using Heavy Metal Map as your mapping program I can see the size limitation issue - but that's the only exception.
