Animated GIFs

A little-known feature of the GIF file format provides the simplest form of web apge animations. If someone creates multiple imaes, each slightly different, and saves them into a single GIF file using a speacial program designed for that purpose, most programs that can display a static GIF can display the animated GIF, much as you might have made flipbook animations as a kid. Animated GIFs are genetally set to loop constanylty, which is unfortunate, since I believe they'd have more impact and be less annoying if they looped just once, or at leat put a significant delay between loops. Animated GIFs are limited in the same way static GIFs are. The beauty of animated GIFs is that they require no additional software. Essentially, animated GIFs are simple, cheap, and probably the most common way of publishing an animation on a web page.
