Not only is the process lossy - it is cumulative as well. We've seen people open .jpg files, save as .tif files - then save them as .jpg files again when someone somewhere requested the file and they were too lazy to locate the original.

Try doing that a couple of times to a nice image file and you wind up with mush. Artifacts on top of artifacts is not a good look for most photos. I can almost hear someone in the background saying "who shot this, anyway"

Jpegs work great as long as everyone along the route knows how to treat them. It pays to educate your clients on proper handling.

A JPEG is a JPEG. The compression is lossy and the greater the compression the greater the loss. Just cos you change it back, it doesn't make it a TIFF again without the compression!!!
