Well, to clarify, do you really mean "size"? I would assume that 
imageRep.size.width == image.size.width (both are in points), but 
imageRep.pixelsWide would be different, if the resolution is not 72 dpi. Did 
you actually check pixelsWide/pixelsHigh?

Incidentally, if your scenario is intentionally working with only a single 
image representation, then it's probably better (and, I'd say, with 10.6 
definitely better) to avoid NSImage completely and stick with just NSImageRep 
throughout the scenario. I don't think there are any API reasons left to prefer 
NSImage, when multiple representations are not at issue, but others may have a 
more informed opinion on that subject than I do.
