Transparent PNGS will, at some point in the future, no longer be a problem in web design thanks to the release of IE7. However, there are millions of people still using <ie7.

I have personally experienced a lot of problems using transparent PNGS as foreground images... but it occurs to me, that this has never been a problem when they were background images.

I'm working up a new template. So far, I am sticking with either GIFs or JPGs.

Is it reasonable safe to make all BACKGROUND images PNGs, or am I better off sticking with GIFs & JPGS (no transparancy on jpg)???

Anyone?

Hi!

I'd not use transparent PNGs for any mainstream theme that IE6 users might still use, for as long as IE8 is not out.

Thanks Garvin. I was hoping background images were safe. Thought I recalled something about foreground PNGs being the most trouble when they lacked dimensions, and dimensions are not usually given for background images. Back to GIFs or JPGs I guess!!

Hi!

You might remember this from the "browsercompatibility" plugin! This one creates trouble with transparent PNGs without dimensions, because it doesn'T properly scale/rescale it. I don't even know if the browsercompatibility plugin can deal with transparent background images, since it only listens on all <img> tags of a page...

PNGs are always a little tricky. Not because of the transparency, I had more problems with the gamma correction data that can be saved in them. Let´s say that the interpretation of this data can have some... interesting effects. o_O
