IE still doesn’t support 8 bit PNG transparencies properly, IE supports only one bit like GIF.

Look at it in Opera or Netscape, just for temporary viewing.. or ACDSee.

Ultimately the webmaster will position the PNG over the color over their choice, flatten all layers and then export as a gif or jpg at their end for best web compatibility.

Photoshop’s support for PNG’s is a bit shaky for some reason in version 6, compared to Corel Photopaint and Macromedia Fireworks.

IN fact you can download a free PS plugin which makes better PNG’s from PS. Not only that, but they also a free jpg2000 plugin!

NG,

I am a graphic designer supplying a Webmaster a transparent logo (with a dropshadow that fades to no color). I am using Photoshop 5.5, but also
have
access to Photoshop 6 (PC). I tried "Save for Web" using transparent .gif, but am not happy with the result.
Then I tried .PNG. I liked the (transparent) result in the Save for Web window – but when I viewed the HTML with image in IE – the entire image
has
a gray background.
Any suggestions?

Thank you,
Kathy

(And it’s implemented in such a way | that any palette index that isn’t completely opaque is treated as | completely transparent–depending on your image, say goodbye to | most of it! To make up for that, MSIE for Windows doesn’t support | 32-bit RGBA transparency at all.)

It’s possible to make it work with a more or less obscure MS filter but IMO it’s not worth it.

The problem is PS5.5 was very poor at handling PNG. PS7 is better but not to hot on compression. With PS your better ensuring your using a web palette and using gif format, this should also provide a much smaller file size than png.

Have you tried changing the settings, no of colours etc?


There are no problems only situations

Actually the problem is that Internet Explorer doesn’t handle PNG transparency. It has little to do with Photoshop.
