Hey, a bit of advice for ye "Gamers' Haven" folk:
Microsoft, the evil entity that they are, are always pushing their campaign to remove compatability with old, ineffecient, or non-Microsoft devices, programs, and file types; their hope is to crush everything non-Microsoft with their market prowess.
Anyway, so far in this campaign, newer Microsoft products no longer support 8-bit color, resolutions below 640x480, most DOS-based programs, all Netscape-based plugins, and, for some reason, bitmaps.
Suffice to say: if you want maximum viewability of your site, I'd suggest you use a file format other than bitmaps.
Go Moon!
