If your photos are publicly available, or you give them to someone else (Facebook, Instagram, etc) you no longer have a privacy interest in them. When you willingly give something to someone else, it is no longer yours. You can have an agreement (civil contract) that you expect that company to keep things private, but they can still voluntarily give them to the police. Your remedy would be to civilly sue them for breach of your contract, but said photos can still be used against you.
