I thought I read that IE6 was supporting Alpha channel png's? Appears not to be the case?
ex: the glass ball [searchengineworld.com].

Or is there a setting I have turned off somewhere?

Just tried it on W2000 - no joy. Maybe it works on XP???

Well, you could try this:
[webfx.eae.net...]

It involves a few extensions that allow Internet Explorer to display alpha PNGs. However, although I did get it to work, now my images appear with broken image frames overlayed on top of the image itself... :(

The Internet Explorer workaround, but removes the image from Opera altogether. Has anyone found a fix by chance?

Because of a 16MB graphics card, I have my color set to 256. When I save glass ball [searchengineworld.com] and open with IE6, the background renders accurately.

It's only if I save to higher color settings (true color) that png files start to have problems. I rarely use png files, but I always attributed this to a cheap v-card.

When using Win98 and IE6 I have no problems as long as my colors don't go above 256. On WinXPPro and IE6 I have no problems as long as my colors don't go above 16bit.

I'm using a 64Mb Graphics Card in both

Brett,

I know you made a long and excellent post on PNG a while back, but I thought I might chime in here with a few things

First (because it's quick): The Official PNG Test Suite of Images [schaik.com]

Second, as for MSIE png compatibility see the
IE Section [libpng.org] of the browser compatibility page [libpng.org] at the official PNG site [libpng.org]. The best page for navigating the site, however, is really the site map [libpng.org]

The browser compatibility page says:

Internet Explorer [Microsoft] (Mac PPC) - version 5.0 and later; read-only; full alpha support (screenshots); full gamma support; full sRGB and ICC profile support; progressive display of interlaced images (replicating method);...

Internet Explorer [Microsoft] (Win32, Solaris/X, HP-UX/X) - version 4.0b1 and later; read-only; broken alpha support in Windows versions 4.0b2 through 6.0;1 full gamma support; progressive display of interlaced images (replicating method); broken OBJECT support;2 MNG support via Jason Summers' MNG4IE ActiveX control; version 4.0 crashes on large PNG chunks;3 version 5.0 prints palette images with black (or dark gray) backgrounds under Win98, sometimes with radically altered colors;4 fails to display PNG images used as CSS backgrounds; sometimes completely loses ability to display PNGs (see FAQ page for various fixes)....
