Gist to document a way to add a MacOS Automator Quick Action which automatically extracts the images inside a ZIP file. This is useful when you pick and download a few images taken from iPhone from Google Photos, and instead of an Image you get a ZIP file. This will extract the images inside the ZIP file and delete the original file.
