poo pooing on jpg format is inane. There is a time and a place for jpg, and obviously you don't do multiple edits on that format. It's also obvious you don't convert low color images to that format if you want it to look good. Consumer cameras save to jpg because people can't see the difference in their pictures between raw because consumer cams don't have the quality for raw to make a difference anyway.
Obviously you do your editing in a lossless format, and when you're done you publish in a lossy format unless your image is line art, screen shots or low color pix of crap you scraped off your amiga. That pic of the beach during sunset is going to look the same to people whether it's a tiff or a jpg, most of human vision is stuff being just plain made up in the viewers brain. This is why people use JPG, the result is about the same and it takes up a lot less bandwidth.
Every file format has it's time and place.
