Download photos and videos you're tagged in on Facebook

Why

When you download an archive of your Facebook account, Facebook includes photos and videos you've uploaded, but not photos and videos you're tagged in that were uploaded by other people. This is a script to automatically download those.

Setup

This requires Python 3.
