::kisses Dodger:: (Don't worry, I'm cute. ^_~) I thought surely there had to be a catch, at least some slight difference when rendering that might matter in some cases, so I tried it out. Opened a bump map I already had on the drive in Photoshop, saved as a jpg, made a Poser scene with two figures, applied the original bumpmap to 1 and the jpg to the other, and rendered. I then switched the bumps, rendered again, overlaid them in Photoshop, and changed one to "difference" mode so I could see any differences between the two renders. And there were none! Except that the original BUM is 3037K and the JPG is 698K. The only problem is that if I try to load the jpg from the material dialog, it wants to convert it. I tried changing the extension to BUM, but it still wouldn't load it. However, I know from past experience that jpg bump maps can be applied in P4 with MAT files (it's usually an oopsie) or referenced in the model in the library. So I think this definately has potential!
