old_contents: """:mod:`wand.display` --- Displaying images
  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
  
  The :func:`display()` functions shows you the image.  It is useful for
  debugging.
  
  If you are in Mac, the image will be opened by your default image application
  (:program:`Preview.app` usually).
  
  If you are in Windows, the image will be opened by :program:`imdisplay.exe`,
  or your default image application (:program:`Windows Photo Viewer` usually)
  if :program:`imdisplay.exe` is unavailable.
  
  You can use it from CLI also.  Execute :mod:`wand.display` module through
  :option:`python -m` option:
  
  .. sourcecode:: console
  
     $ python -m wand.display wandtests/assets/mona-lisa.jpg
