If I start with an image out of my digicam and it is already in JPEG format I'll save it as an .xcf or .xcf.gz. When I'm finished makin changes then it gets prepped for the web. (crop, scale, and jpeg compression) The only manipulation I can think of that would benefit from "lossless" jpeg would be rotating the image. (if I were shooting low-rez) I remember seeing some tools at the JPEG F.A.Q. site that would rotate a JPEG without damage. http://www.faqs.org/faqs/jpeg-faq/ Tom Lane!
