Well, I always find that in PS 6, jpegs tend to look a lil'different elsewhere than on photoshop, no matter what the compression levels. Dunno what the prob might be. Also, doesn't photoshop use its own gamma settings? As far as I recall it does. When photoshop is closed, or yer not viewing the image in photoshop, the gamma and colour settings likely follow what you have your video card settings set to. just a thought.
