transparent png's

I use pngs rather than GIFs because of the legal problems. All works well for my linux browsers but I hit problems with IE !!

To get a transparent png which works with IE I have to ...

draw it in the gimp, save as gif ... execute ... gif2png utility
and hey presto my image works in IE with transparency.

However if I draw in gimp and save as png, all is ok in linux browsers (all of them!) but it does not work in IE

Any ideas how to streamline this so I can save from gimp and it all work ?

IE on windows doesn't render RGBA PNGs properly (unless you want to use this kludge:
http://support.microsoft.com/default.aspx?scid=kb;en-us;Q294714). You can use 1bit transparency PNG similar to what GIF provides. In GIMP index the colors before saving as PNGs (You don't need to do this for GIFs, because Gimp does it for you, GIFs can't be RGBA).

cheers
