- Now go to the option View Photos of Me and open the image in which you wish to untag yourself.
- Under the image you will see your name, and next to that you will see the option Remove Tag.
- Click on this to untag yourself and the process will be completed.
There you go. That was all the information on how to untag photos on Facebook that you need. There are some quirky rules that Facebook has about the whole tagging and untagging business, but you can go to Account Settings and then Privacy Settings on the top right corner of your homepage and alter settings as you see fit.
