JPEG Quality Changes

These JPEG images were created from an initial 24-bit color image with millions of colors. Note that as the quality of the JPEG image is reduced, artifacts (little dots or "measles") can be seen around the final image.

The artifacts will be more obvious if your monitor is set at 256 colors. Quit your browser, reset your monitor.
