Use the appropriate format for the image. Generally, photos are best in JPEG, diagrams in PNG.

If you're just aiming at E-Ink screens, converting colour images into high contrast greyscale can also help. (By choosing the colour->greyscale conversion carefully you can obtain a better result than relying on the default conversion in the ebook reader.)
