Oh, there are other options then just resizing the image. The reduction of the image size is not as effective with JPEG as increasing the compression ratio. JPEG transcodes images to a digitized set of wave samples. By dropping the least significant parts of the wave parameters the images gets some small errors, but becomes much smaller. By bringing the image closer to a wave (i.e. reducing the pixel-to-pixel contrast) using a "gaussian blur" or "softening" filter you can further increase the compression ratio. I have usually enough phantasy to be comfortable with a 100k size for real world JPEG images of any size. ;) Dirk. -- There are two major products that come from Berkeley : LSD and UNIX.
