The only advantage GIF has over PNG is animation support (which is what MNG is for).
As for PNG vs. JPG, PNG can use a lossy compression scheme just like JPG and any compliant decoder will still read it fine. Thing is, you need to convert 8-bit images (such as ZDoom screenshots) to true-color for lossy compression to work (so you'd effectively triple the source image size before compressing).

It's still there.
OK, same picture made by PSP - one PNG one JPGKillo Zapit wrote:JPEGs suck and are evil. Don't use them. Ever. If you use JPEG your penis will fall off. Use PNG for images on the web.

JPG = 32.5KB
PNG = 222KB
Obviously quality is an issue, but quite often it doesn't matter. However, in many cases - especially for "images on the web" - a graphic being almost 7 times bigger than the other option is important.
In fact, reducing the picture to a paletised one and saving as a PNG and a GIF still left the JPG as the smallest file.
PNG = 46.8KB
GIF = 47.1KB

In case it came across as me arguing for JPG screenshot support: I think that would be a waste of time and effort. If I want to have my screenshots in JPG format for posting somewhere, it only takes me a few seconds to convert them. A lossy format for stuff that is saved to you HD (where space and speed is not an issue) seems silly and pointless. Having a good quality original shot seems for better even if I am going to convert it to a JPG for some other purpose.
