    # THE THUMB VERSION IS NECESSARY BY ADMINPANEL, DON'T REMOVE IT!!!!
    version :thumb do
      process resize_to_fill: [120, 120]

    # however, you can create your own versions:
    # version :awesome do
    #   process reside_and_pad: [120, 900]
    # end

    # EXAMPLE:
    # original 300 x 300 (this is a square, thanks)
