What browsers do not support PNGs yet? I know from experience that NN7, NN6 and IE6 support PNGs..

What about the other browsers? Do they support PNGs and one of their key features which I am about to use to design a portfolio site - 254 levels of transparency?

Before referring me to alistapart.com,

From alistapart.com

"Which is a shame, because PNG makes GIF look pretty pathetic: it supports gamma correction, (sometimes) smaller file sizes, loss-less compression, up to 48-bit color, and, best of all, true alpha transparency."

"It turns out that most of the latest versions of the major browsers fully support alpha transparency with PNG – namely, Netscape 6, Opera 6, and recently-released Mozilla 1, all on Windows; and, for the Mac, Internet Explorer 5, Netscape 6, Opera 5, Mozilla 1, OmniWeb 3.1, and ICab 1.9. Incredibly, PNG even works on Opera 6 for Linux, on WebTV, and on Sega Dreamcast."

I've tried it in mozilla in linux and it works perfect. Not tried it with opera and netscape 6 though. I am definite it works in netscape 7 ( including 256 levels transparency ) and prolly IE 6 ( don't have that installed yet ).

YES! alistpart answered part of my question... but I need more uptodate info. Do IE 6 / Firebird / Opera 7 support PNGs?

The prob. is...

"IE5.5+/Win, bless its heart, will, in fact, display a PNG, but it doesn’t natively support alpha transparency. In IE5.5+/Win, the transparent area of your PNG will display at 100% opacity – that is, it won’t be transparent at all."
