I see what Seph3D means.
<- PNG, as viewed in Internet Explorer 6.

If you take the Netscape 6 one and zoom in real close, you can see how it does the transparent kinda thing on the background around the edges - the image will look good
no matter what color background it is on.
This isn't enough to make me switch to Netscape, though :-p
[Edit] Whoops, forgot the second "!" in the path to my images...
