> Guideline 7 at http://www.w3.org/TR/WCAG10/ says > "Ensure that moving, blinking, scrolling, or auto-updating objects or pages > may be paused or stopped." and > "Until user agents allow users to freeze moving content, avoid movement in > pages." > > How does this apply to animated GIFs? [IMHO:] Animated GIFs can feature moving, blinking, or scrolling, so if you use them and do not have an adequate form of control, you are in violation of the guideline. I suppose you might be able to have a link with some scripting hack to turn off the animation, but that wouldn't work in some browsers, so you still couldn't cionsider that you have passed the guideline. I bleieve the rationale is that some people can't focus on moving images, or blinking lights cause them discomfort, or even seizures (flickering is a P1, everything else P2). Animated images are a nuiscance to many, and you have to ask yourself if there is anything to be gained in having them in your Web page. Is there information in there that can *only* be displayed using an animation? Can't you link to it? -- Kindest Regards, Sean B. Palmer @prefix : <http://webns.net/roughterms/> . [ :name "Sean B.
