Pro pack will NOT convert jpg's to BUM's Only the regular P4 did that. Pro Pack and Poser 5 uses a bum if it's there, but otherwise it uses the jpg. I think there's some way om making a green image and name that bum. Something with bums really being weird bmps... But I don't remember. It's been a while since I read it and since I had Pro Pack and P5 I didn't really bother.

You just can't put the words "Poserites" and "happy" in the same sentence - didn't you know that? LaurieA
