How do you permanently delete facebook profile picture photos?

[Raven Lee]

Hello, I have a horrible picture of me on facebook profile pictures and I would like to delete it. I have tried going to the bottom right of the picture and have clicked 'Delete This Picture' but every time I try to it just comes back. I'm not tagged in the picture because in the bottom right hand corner it says 'Tag This Photo' but I really don't know how to permanently delete it so it doesn't come back. How do I do it?
