Abstract:

While image rollovers are the standard for navigation, they do have some limitations. Would you like to create a rollover that doesn't have to be the same size as the original image, nor does it need to be stacked on top of the original image? That's what disjointed rollovers are all about, and Flash makes it easy to create rollovers that load quickly and look great!
