This common and small data picture apparently is the best format for casual photographers who shoot, print, and share without much serious editing. PC World Gurus recommend setting your camera to capture pictures at hte lowest compression, which equates to the highest image quality.

Here's the downside: everytime you make a change to a photo and save it, you are reducing the quality of the image. IT's like making a photocopy of a photocopy. The loss of detail will become obvious with time.
