We have complete control of photos which we upload on Facebook. But not on photos which are uploaded/tagged by others. Your friend may choose to delete your photo anytime without your knowledge. It is a good idea to have your own backup of photos of yours which are tagged by others.

We will achieve our desired task by using ifttt.com (If This Then That), which automates the whole process. If you don’t have a Dropbox account already, go signup for a free account before proceeding. So let’s get started:

1. Signup at ifttt.com if you haven’t already
2. Goto http://ifttt.com/channels and activate Facebook & Dropbox so that ifttt will have permissions to access your accounts.
3. Goto this recipe http://ifttt.com/recipes/1760
4. Change your Dropbox folder path if you wish to & click on “Create Task“. Don’t change anything in File URL.

And you are done, next time when someone tags you, that picture gets automatically uploaded to your Dropbox. If you have Dropbox desktop client installed, all these pictures will automatically appear inside your Dropbox folder. One limitation of this ifttt task is that it works only for photos which will be tagged from now on, it won’t backup photos which were tagged before creating this task.
