+#### [Linux] The script hangs and doesn't display anything
+
+This is caused by the getwallpaper function failing to find your current wallpaper and <br \>
+imagemagick trying to crop a nonexistent image. You can fix this by installing feh and using it<br \>
+to set your wallpaper or by changing the image source.
+
+You can change the source by editing the `$image` variable. The possible values are:
+
+* **wall** - Use the current wallpaper.
+* **shuffle** - Shuffle through images in a directory. See `$shuffledir`
+* **path/to/img.png** - Select an image to display.
+* **off** - Disable images
