PNGs
.PNG is a file format that is open source and was never widely adopted for web use. Macromedia uses it as their default file format.
:
First of all, no one owns the format because it is open source (unlike GIF's and JPEG's)
Secondly, they support transparency and also drop shadows can appear like shadows, unlike when a GIF makes a drop shadow it does not make transparency under it
Finally, it has great compression.
Now, why did this not really catch on as it should have done? <img src="graemlins/smokin.gif" border="0" alt="[Chilling]" /> <img src="graemlins/smokin.gif" border="0" alt="[Chilling]" />

And how about the support, ie lack thereof, in IE for Mac. When the fsck is IE 6 for Macintosh coming? That would be a good feature to add. (providing it's full-assed of course)

I don't believe that IE supports animated PNG.
I'm guessing PNG hasn't caught on as much as it could because people are lazy.
Windows Explorer can even show the transparency, them screwing it up in IE is beyond lame.
<strong>Because it's not as extensible as JPEG in major apps like Adobe Photoshop</strong><hr></blockquote>
I'm intrigued by this comment. Care to expand?
Also, does anyone think jpeg2000 will meet with the same apathy as png. I think they are both very cool and would like to see Apple make use of both. Does anyone know if you can set .jp2 files as desktop images in Jaguar?
Do the same for "Save As."
<strong>IE for Mac has always had the best PNG rendering.</strong><hr></blockquote>
I was just on the Macs in our computer lab the other day and IE 5.2 for OSX couldn't open a PNG that someone posted here. So I don't know what you are talking about.

I know that, but MNG is animated PNG. Just a different extention.

--it's a png, with levels of transparency. IE5 for Mac has been way ahead of the field with this all along. See:
<a href="http://www.libpng.org/pub/png/pngs-img-ie5mac.html" target="_blank">http://www.libpng.org/pub/png/pngs-img-ie5mac.html</a>
also. Now do you know what I'm talking about?

I right-clicked on that logo in IE 6.0 on Windows and it wanted to save it as "transparent.gif"... <img src="confused.gif" border="0">

<strong>That would be because I'm using this cunning hack to get around IE/Windows' deficiency:

from the link: "Mozilla 5"
This is news to me! Mozilla jumped from 1.0 to 5.0 in a matter of months?! Take THAT IE!
Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en-US; rv:1.1a) Gecko/20020610
So the page is correct. Do you see?
