Now that you have made all the layers 80x80 pixels (supposing you have), you will have to do one of two things. If you have elements, go to file, save for web. Then set as gif, animated, and set the speed. Save. It is easiest in photoshotp elements, so if you got cs2, download elements trial version off adobe's site.
In CS2, it is surprising more complicated; you have to use image ready (a photoshop feature). I currently don't have CS2, so I don't know how to work it.
In the end though, the resoloution may not be wonderful...you'll want to see how it ends up.
