Hmm.... well if you save it as png actually that might not work. Try it as a gif, and if not, save it as a gimp or sai file with all the layers intact. That way people can take each frame and colour it, or duplicate the frame and over lay them (as I would be doing). I don't know how to work flash, otherwise I'd have some better advice XD I know some people make a big png file with the layers set out next to each other so they don't overlap, which is like uploading each frame individually but then compiling them into one image. That should be doable too. I don't think there is a good way to condense them all down.
A baby bounce cycle would be perfect! hhhhhhhhh....
