  I just tried to compress a 4096x4096 image to PNG with pngcrush (using its
brute force search for the best compression settings).
  At 24 bits per pixel the image file is 58540 bytes long, and at 8 bits
per pixel it's 2131 bytes long.

  (I really wonder why the 24-bit image is so big. Why not three times the
size of the 8-bit version?)
