Animated images are more taxing on resources, just look at any of those animated gif-laden threads, they're a nightmare. Then, imagine that on EVERY thread. Nothing like having a bunch of annoying, flashing, distracting images pulling attention away from the actual content of the posts.
Not to mention...they're tacky. Awful flashbacks of 1990s era angelfire sites (or today's myspace sites, ha) loaded with a bunch of random ass animated gifs.
Sure...some could be artfully done, like the sparkle on my halo, would be nice if it had a subtle twinkle. But, what's to stop a bunch of people from making horribly done, epileptic seizure-inducing monstrosities? I'll stick with static images thankyouverymuch.
