They support RGB pngs, but not RGBA, and they support Indexed PNGs with GIF style transparency, but not multiple palette entries with different alpha values. I'm afraid I know nothing about IE/Mac. I have never been a mac user. For example images to test IE against this, have a look at this enhancement request... http://bugzilla.gnome.org/show_bug.cgi?id=86627 Cheers, Dave. -- David Neary, Lyon, France E-Mail: [EMAIL PROTECTED] ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

[Gimp-user] transparent PNGs in IE
I know there's already been a lot of discussion on this subject and I've read pages and pages, but I'm still unclear. I realise that just about all recent browsers support PNGs. But, is it or is it not possible for IE (v. 5, for example) to correctly display a PNG with a fully transparent background so that anything behind it shows through? My PNGs are OK in Mozilla, Netscape, Opera, Konqueror and Nautilus, but in IE they have a rectangular white background that completely wrecks the effect.

You can achieve 1-bit transparency for example. Mukund ___ Gimp-user mailing list [EMAIL PROTECTED] http://lists.xcf.berkeley.edu/mailman/listinfo/gimp-user

To do so, you need to make sure that your png is saved as an indexed image, rather than rgb (which png supports, but gif doesn't - this is why when you save as gif, you get a dialog asking you if it's OK to index the image sometimes). To do this, go into the Image-Mode menu, and select Indexed as the mode of the image. Then choose a palette to use (automatic is usually OK), and save as png as you do normally. The GIMP's png support is limited somewhat by its core support for indexed images - you can have one index entry completely transparent, but partial transparency (which is supported by png) is not supported for indexed images in the gimp.
