This script will navigate through each photo in the "Photos of You" tab and click the download button.
It appears to be typical for videos you are tagged in to not be downloadable. *These will be skipped.*
Navigate to the "Photos of You" tab of your photos page. In a few moments, a "Download All Photos" button should appear to the right of the pencil icon button ("manage"). Click the button to begin the process.
*IMPORTANT*: Be sure to configure your browser to download files to a specified folder without confirmation, otherwise you will end up with a confirmation popup for each photo download!
Use at your own risk. :)
