If you have Linux installed and running, you may also have ImageMagic (if not, get it and install it). Use the mogrify option to resize an image to a smaller size. Resizing to a larger size is limited (eventually images begin to blur). You can always go smaller and retain a sharp image; going larger has its limits.
PS: there is a difference between compressing an image and resizing an image. Compressing can be a problem, becausing some image formats are already compressed. Resizing, on the other hand, changes the size of the image, but doesn't compress the image. Failure to grasp the difference means failure in your attempts to get the image in the size you want. Compressed = smaller file size; resized = smaller image size.
