Safari differs from Firefox and IE in how it displays the GIF I'll attach momentarily. In Firefox/IE, the image has a transparent background, with a blue fill/red stroke square moving in the middle. In Safari, the entire background is red. I haven't checked, but I suspect the GIF has red as color 0 in its palette, and Safari is decoding anything that should be "background color" as color 0, while Firefox/IE decode that as "transparent".

Same results on Mac (Tiger), which would be an OS bug if reproducible on Leopard.

This appears to behave differently in Leopard than was described for Tiger. Image decoding is not handled by WebKit so I suspect that this bug belongs in Radar instead.
