Wallpaper was not created since there was no module named 'PIL'.

What was expected:

Setting wallpaper...
Wallpaper set successfully

What happened:

Creating wallpaper...
Traceback (most recent call last):
  File "/home/michael/process-wallpaper/generateWallpaper.py", line 2, in <module>
    from PIL import Image
ModuleNotFoundError: No module named 'PIL'

Setting wallpaper...
feh WARNING: /home/michael/process-wallpaper/wallpaper.png does not exist - skipping
feh: No loadable images specified.
See 'man feh' for detailed usage information
Wallpaper set successfully.

My Verdict: The "PIL" module appears to be depreciated, and the wallpaper is not created.

There is no problem with the package. You didn't install the requirements.
