Okay, I did some short tests: -- 1st test: waterfall.png (an example for a normal photograph) 718K Jul 17 15:33 waterfall.image.bz2 649K Jul 17 15:32 waterfall.png -- 2nd test: bio_hazard.png (an example for line-art, where png shines) 9.2K Jul 17 15:35 bio_hazard.image.bz2 21K Jul 17 15:35 bio_hazard.png In both cases, the imagefile+bz2 wins (due to reasons I gave in my last mail). Compressing the png's with bz2 obviously has only a minimal effect, because the compressor can't look through the interweaved png-format. You can check out the files I used here[0].
