New Post: Loop through images to simulate video

So I have a series of 20 weather images (GIF files with accompanying world files) and if I load one it looks great on my map. What I am trying to do now is simulate a "video" of the weather as it moves. My first shot is going to be to loop through each image, open each image, clear the image layer, then load the new image into the layer. Is something that someone has done before and if so whats the best approach to do this kind of functionality?

Thanks,
