True, but the point is that any image that is not "photo-realistic" - ie that contains lines, text, and blocks of a single colour, rather than continuous gradations of colour - will compress to an enormously smaller file with GIF or PNG than with JPEG. Try it for yourself. Eg, take a screenshot of this MR screen, and save it respectively as JPEG, GIF and PNG. The results may surprise you!
