What's wrong with PNG files? Options

[*The Markster*]

I realize that people can still use PNG files because of their high reliability. But aside from the fact that, for an unknown reason, many are neglecting PNG files and looking up to GIF files instead, is there anything technically inconvenient with PNG files? I do know that some browsers experience alpha transparency issues with them, but I've heard that there's some fixes too. But I'm not really sure. xD

So yeah. Could someone please tell me the pros and cons of it, and if they have fixes? Thanks.

I don't know what the fixes are, but there is a PNG/GIF (as well as PNG/JPG) comparison on wikipedia.

Edit- Actually, what Lucy (a beautiful nothing) meant was this script which fixes the transparency issue in internet explorer, not firefox (as firefox renders png transparencies correctly).

Thanks a lot. This really helps.
About the IE alpha-transparency fix, does that fix Internet Explorer 4-6?

I ALWAYS use PNGs. Only because GIF pixleate my images, and JPG's turn into HORRIBLE quality.

JPGs horriblify your pictures? Hm. Doesn't it work well if you set the JPEG quality to 100? I usually do that to my real-life images, as well as certain of my Myspace layout images.
