Thumbs down spur of the moment essay on why png sucks

Bah! I've never liked PNG/MNG encoding. My experience with animated GIFS and Netscapes semi-priporitory animated JPEG format is that MNG is usually 10-30%+ larger. I can _always_ get non-animated GIF/JPEG smaller than PNG. Granted, when 24bit is required (which it usually isn't) JPEG is what I'd use and a level 5-7 compression which does cause jpeg artifacting. JPEG was build for photographs. A photograph at 300+dip even with level 5 compression the artifacting isn't bad. Now a screen shot as 96dbi (which is a screen shot) is will cause great jpeg artifacting so I'd use GIF w/ LZH compression. Graal very rarly has more than 256 colors on screen at any given time even when 3d lighting effects are used. When saving a GIF, the image editor can adjust the local palete so you can still see all (or 90%+) of the colors used in the 3d effects. After this you can use a GIF compression utility to remove all extra colors in the palete that aren't used, thus making the file even smaller. Other than on photographs, I don't need to see 16 bloody million colors in prestine quality.

PNG sucks !
