Currently canvas doesn't support handling of GIF. It's basically a video and not really an image as it has several frames. When using canvas to resize a GIF it only cares about the first frame. This is fine when using GD as know GD can't deal with GIFs and will do the same thing. However ImageMagick can handle GIFs. The JS should probably skip client side resizing for GIF IF the image software is ImageMagick.
