JPEG Format - About JPEG and JPEG 2000 File Formats
JPEG (or JPG) stands for Joint Photographic Experts Group, and was named for the organization that developed the format. Here you'll find information and specifications on the JPEG (jpg) and upcoming JPEG2000 (jp2) graphic file formats used on the Web and in digital photography. Includes software for working with JPEG images, technical specs, news, answers to frequently asked questions, and tips for working with JPEG graphics.

The Pitfalls of JPEG Compression and How to Deal with It
Understanding JPEG compression will help you deal with it. Most mid- to low-range digital cameras save images to the storage card in JPEG format. This is a compressed file format that permanently, irreversibly loses quality each time the image is saved.

JPEG2000: the Killer Image File Format for Lossless Storage
"Is JPEG2000 the killer image file format for lossless storage? Ken Milburn thinks so. In this article, Ken details the options available in the JPEG2000 plug-in, which have been designed to help photographers losslessly compress and store the highest-quality images as efficiently as possible."

JPEG and Exif - Digital Camera File Formats
Digital cameras use a variation of the JPEG format called Exif that allows additional picture information to be stored with the image. This article from Ulead explains how to display and preserve this information.
