Yes but the spec doesn't say how it should be rendered. If you're gonna
change the size of an image to something smaller, you're obviously gonna
lose some sharpness/detail/etc., just like making it bigger won't result
in a more detailed picture, you'll just end up with a pixelly mess.
For testing purposes, I saved the header.gif image and made my own
little testcase, a simple body and an img tag, with the height and width
you specified. I then checked the resulting page in Photoshop, measuring
the header.gif's size. Mozilla *is* resizing it to the specified height
and width, so I don't see a bug...
Offtopic question: why resize it in the first place? Why not just crop
it to the size you want. Results in faster rendering of the page, as any
browser that encounters the page won't have to resize it first.
