Yeah, GIF sucks. 8-bit color is definitely not good enough for pr0n.

I remember the days of GIF pr0n.

I'm a PNG and JPEG man. I really love PNG for my photography, so I can provide 24 bit, lossless versions of pictures easily. JPEG is good for providing nice small lossy versions of my photography.

Keep in mind, I would rather send a 5MB PNG, than a 12MB RAW or 15MB TIFF :P
