A couple of comments:

1) JPEG is suitable for photos of natural scenes, but for scientific
graphics with lines, sharp edges, solid colours, PNG is better.
ImageMagick will produce either.

2) One of the advantages of the ImageMagick convert command is that
you can use it to reduce the number of colours in the image, where
appropriate. I normally produce PNGs from IDL in 24-bit colour, but
often reduce them to 8-bit or 4-bit colour with ImageMagick
afterwards, if file size is an issue.
