So, what's up with IE's handling of pngs? I'm trying to use some to get transparency and still be able to have more than 256 colors. It works perfectly in Firefox, but in IE they're not transparent. To see, check out http://test.virocolor.com in both. I'd rather not switch to gifs, but if that's the only way, I can (it'll just be work redoing a bunch of stuff). Or is there something else I'm doing wrong?

edit: So, I googled and found a bazillion pages. Turns out MS never fully implemented PNG support in IE for windows - there's no proper transparency supported. It's either use gifs or one of the many workaround people have found. However, there's problems with all of them (speed hits, reliance on JS and other scripting, etc) so I guess I'm back to gif. Too bad - it'll look much worse than png would. I may actually write it so anything BUT IE sees the png, but ie gets fed the gif images.
