how to delete picture off facebook?

[Linda]

I posted a picture on my friend's facebook. They don't want it on their account. How do I delete the picture?

[anon]

The way you do it is you post a copy of the same picture again and they will cancel out

go back to where the picture is, and hover your mouse over it, and a little X should appear in the corner

click it

or are you saying that you tagged your friend in a picture you uploaded? that's not quite the same thing
