Changing compression rate and changing size aren't really the same thing. Your original question was on compression. A lot of graphics images are already compressed and it's tough to get them any smaller with a Winzip like utility. Your success will depend on the format you use. The best approach is to save as a different format. PNG gives good compression ratio whereas BMP does not.JPEG And GIF should give similar rates of compression and file size for like images.
