How to make image move vertically?

How do I turn a picture into a gif image and make it move around and change colors and stuff? I have Photoshop version 5.0 if that matters, but I'd guess it would be pretty much the same function in any version.

• Answer:

  Animated gifs are actually a type of "movie". Imagine one of those sketch books you may have seen as a kid, with an image that is slightly different than the next, in order. When you flip quickly through them, voila, a moving picture. No different here. You can do it in Photoshop, by maninpulating a base image in layers. Each layer is a page in that sketch book. You have the ability to vary the speed, for your motion. I'm afraid you may have to do some drawing unless you have the images already made or copied from another file format. My avatar, for example, used the dive flag for a base and the fish image was superimposed on each layer, in a different position to the end and then looped so that it began again. If you don't loop it, it'll do the sequence once only.
