You can find out how to delete photos and tags on Facebook here..
You can easily delete your photos on Facebook and on most devices. Markings on other images can also be easily removed. In this guide we explain how this works with Android, on the iPhone and on the computer.
Deleting photos from the profile works a little differently with each operating system or on the desktop:
Android
iPhone
Desktop
If you've been tagged on a photo and don't want to be, you can't delete the photo itself, but you can un-tag it. This works the same with Android devices, on the iPhone and on the computer and only looks slightly different.
