  # resize_to_fit
  # Resize the image to fit within the specified dimensions while retaining the
  # original aspect ratio. The image may be shorter or narrower than specified in the smaller dimension
  # but will not be larger than the specified values.
  #
  # Probably best for taking a big image and making it smaller.
  # Keeps the aspect ratio
  # An uploaded image that is smaller will not be made bigger.

  # Resize the image to fit within the specified dimensions while retaining the

  # Keep in mind, resize_to_fit will scale up images if they are smaller than 100px.
  # If you don't want it to do that, then replace that with resize_to_limit.
