Send a counter-notice
Use this if something you posted was removed after a copyright complaint and you believe that was a mistake — because you own the work, because you have permission, or because the complaint identified the wrong thing.
Read this first
A counter-notice is not a private message to us. By law we pass your name, postal address and telephone number to the person who sent the original complaint, and if they do not go to court we put the material back in 10 to 14 business days.
So this is the wrong form if what you want is for the photo to stay down, or if the person complaining is someone you would rather not give your address to. If a photo of you was posted without your consent, use the report form instead — nothing there is passed to anybody.
