Yup, and I was talking through my hat when I was talking about IE supporting

Actually, no. That's how indexing works in the GIMP. But it is possible to have
alpha-blended indexed images in PNG. PNG indexes may have an RGBA value, as
opposed to just the RGB value that we limit things to. Here's the bug jimmac
opened about this, with a couple of examples of indexed pngs with nice alpha
channels. http://bugzilla.gnome.org/show_bug.cgi?id=86627
