The PNG compression is not as good (size wise) as jpg but it's lossless which is great were we need to retain original image quality. In one test I found that jpg can get a compression ratio of about 9:1 without any noticable artifacts on scenery textures. (90% quality in GIMP) The same texture file compresses at about 2:1 using PNG. Maybe not ground breaking stuff but certainly better than raw image files and it's free of any patents.
