I have no problems going along with any of that (that you can't see any difference, or that Gimp can make a big change), but any time you save a JPEG, it's a lossy compression (once when the camera made the JPEG, once more when you re-compress it through the Gimp, and then anything else you do to it). It's not something I'd recommend someone to do ad hoc. Sure, if you're never going to do anything more to a picture, it's not too bad to do, if you need to save on drive space. But if you ever intend to edit the image, you've already lost one generation. How much you'd save would depend on how you've set the Gimp to save JPEGs, anyway. -- (Currently running FC4, occasionally trying FC5.)
