Dbrudick,
ah! scratches ear oh well...sigh.... throws calculator into the bin ;)

I have seen some images where the bump is a truly different map (not just a desaturated colour map copy) and those are good, but not too common.

NPB, mate :)

AboranTouristCouncil,
You cna lower the quality of the jpg export, but as always, it's a trade off between quality / file size.
Bump maps are ESPCIALLY bad if you lower quality, you see too many angular jpg artifacts, bump maps are better as lossless formats, even if file size sucks.
