[WSG] PNG support cross browser
I understand the limitations of alpha transparency and 24 bit png, but is it safe to use 8bit png in place of gif files? which browsers won't display an 8bit png (no transparency, just for the smaller file size)? a definitive table would be great... I've searched, but info is either old or confusingly written.

You can get problems with colors not matching between PNG and HTML/CSS colors. It has to do with Gamma values, read more here: The Sad Story of PNG Gamma Correction http://hsivonen.iki.fi/png-gamma/ /AndersN *** List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: [EMAIL PROTECTED] ***

I recommend PNGOUT - http://advsys.net/ken/utils.htm (Mac OS X and Linux versions are available - http://jonof.edgenetwork.org/index.php?p=pngout) It's slower than pngcrush/optipng, but has excellent compression and removes problematic gamma information in the process. -- regards, porneL *** List Guidelines: http://webstandardsgroup.org/mail/guidelines.cfm Unsubscribe: http://webstandardsgroup.org/join/unsubscribe.cfm Help: [EMAIL PROTECTED] ***
