PNG

What are the advantages and disadvantages of using the PNG image format?

Basically, it's patent-free, it can offer better lossless compression than GIF (I don't know how true this is), it can use alpha channel transparency - in other words, degrees of opacity like a PSD layer.

Disadvantages probably include less widespread support than GIF, but this is rather insignificant since practically all of today's browsers support PNG. Internet Explorer doesn't support alpha transparency though, and that's the main reason that feature isn't often used.

GIF, which is what PNG is primarily supposed to replace, is simply old and it's time to throw it in the garbage.

Here's the official PNG site if you haven't looked at it already http://www.libpng.org/pub/png/

Wow, thanks for the info. That's exactly what I needed. :-)

I would normally move this to beginners corner as it has nothing at all to do with vector/illustration, but seeing as you have had your question answered it may as well stay here...
