In high colour (65,536 colours) mode only every 256th tint can be
displayed, so you have such "steps" on your image. I opened the page in
IE6/Mozilla 1.0 on Windows and saw no difference between both. IE as
well as Mozilla displays the image in several gray strips.

(Maybe IE/Mac has a built-in differing in high colour mode?)

Best regards.
