When you've got some text you want to save against a colored background, which format should you choose; GIF or JPEG? This example will show you which is best and how to do it.

The image to the left is a transparent GIF in a colored table cell. It was saved against a background of identical color in MIC. That color was then made transparent.

The image to the left is a JPEG, saved with almost no compression, against a colored background sampled directly off this page.
