Not to get back into PNG topic too much because I think the image formats question has already been resolved by the style group ;-) but lots of web users (including libraries) have not upgraded to IE7 (or even 8).
W3C reports for July 2009 IE7 15.9% IE6 14.4% IE8 9.1% Firefox 47.9% Chrome 6.5% Safari 3.3% Opera 2.1% These numbers more or less mirror what I've been hearing/reading in addition to the site stats for which I have access. 14.4% seems small (and it is shrinking) but that could still be a lot of visitors. from: http://www.w3schools.com/browsers/browsers_stats.asp I don't think legacy software should CONTROL design, but one part of design is how it will render across a variety of platforms. ;-) So, that is the only reason I mentioned the IE6 workaround as well as the potential PNG transparency problem. I confess -- I am not an IE user unless you can count the few times I check a website for potential design issues in IE6 ( and 7). Yeah, I do know better than to believe that "support" or "compatibility" always mean what I think they should -- LOL (I've had to search for too many hacks, codecs, workarounds, and mods in my life...) IE8 seems to be a step in the right direction, but it's hard to know ... and then there is Chrome, Google's baby -- no telling if that will catch fire. happy Saturday. ;-) On Fri, Aug 14, 2009 at 1:13 PM, Nathan Eady <[email protected]> wrote: > web gurl <[email protected]> writes: > > > From my perspective -- image file formats IE6 is notorious for not > > rendering PNGs properly > > At this point, even Microsoft doesn't really support IE6 any more. > > Well, they SAY they do, but in practice the level of actual support > fell off to basically nothing sometime between three and five years > ago.
