Animation is the way to go.
Here I'll try to explain simply how animation works and how you can make animation. An animated GIF works just the same as any other GIF file. The same HTML code is used, it is just that when the GIF is loaded it animates. The animated GIF is simply a series of pictures run together, where you can vary the interval at which the pictures change. But this does not mean that all software can make and view animated GIFs, most image editing programs cannot.
