IE 6 still doesn't support png's, despite M$ bullshite promises, and PNG is blatantly the best image format, hands down. [beb72a]I[/beb72a] don't call that compatible.

it displays PNGs, but it doesn't do the alpha transparency properly
and it does seem logical to support full apha transparencies now that icons in winXP has full alpha transparency support

What the browser supports is quite seperate to what colour depth the icons can be.
For example, Win98 doesn't have 24bit RGBA icons, yet Mozilla will render them no probs (24bit RGBA pngs that is...).
But IE6 was just and XPified release of 5.5.. and infact I should have lumped 5.5 with 6... and 5.x changed to 5.0x. Blah.
There's hoping for IE7 to be uber spiffy.
Only annoying quirk for me using Mozilla is that it doesn't like:
[code:1eb72a]
table {
border-collapse: collapse;
}
[/code:1eb72a]
No probs with Opera6 or IE.
