This isn't true. Animated images usually don't throb and flash at the right rate to produce seizures. Those which do are banned, but other animated gifs are not. The main access problem with animated gifs is that it's hard to convey all the textual content if there are many frames to the animation. The main usability problem with animated gifs is that they're distractive by their nature, and should therefore only be used when you specifically want to direct the user's attention and prevent the user from doing nearly anything else. --Kynn -- Kynn Bartlett <kynn@idyllmtn.com> http://kynn.com Chief Technologist, Idyll Mountain http://idyllmtn.com Web Accessibility Expert-for-hire http://kynn.com/resume January Web Accessibility eCourse http://kynn.com/+d201 Forthcoming: Teach Yourself CSS in 24 Hours
