Alternatively if the image is bigger (in pixels) than it needs to be
you can reduce the size of the image, in Gimp, using Image > Scale
Image.  Reducing the number of pixels will reduce the size of the
file.  If you make it half the size in each direction then that will
reduce the size of the file by approximately 4 times.
