~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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
.. versionadded:: 0.1.9
