Nicly done Terry on a very dim object.
To create an animated GIF. You will need a program like FireWorks or Flash to create a sequence of them. You just load each image into a layer and give the layer an interval to play before it moves onto the next layer. Then simply export the image as a gif file.
Try Google for specific programs for creating an animation. Although I haven't made one yet, give it a try and see how it goes.
Hope this helps
