When I have a red edge it shows up as a solid red in PNG and GIF formats, but has a black border when rendered to JPEG.

This is an artifact of JPEG's lossy compression algorithm. JPEG isn't very good for line drawings. PNG is bitmap format of choice. John Ellson wants to deprecate and eventually remove the JPEG driver, but North is reluctant to change anything that people might already rely on.
