    # Resize Images in Directory
    #
    # Provided target frame size (TARGETX, TARGETY) this script will scan current
    # directory and scale up an image (keeping same ratio) to best fit. I used
    # this to fix images for a photo frame that would only scale down images but
    # would not scale up.
