I'm thinking if the response is an animated GIF, of type image/gif, why forbid a <video> element from being allowed to play it as a video. I'm also thinking, why forbid other image/* types from being played as static videos. After all, sometimes single-frame video/* files (such as an MPEG single I-Frame) are sometimes created for this purpose on real video players. It would seem odd to allow the display of single-frame video files, but forbid image/* files from behaving exactly the same way. -- Jamie
