First, calling the police on them for such a reason would be an abuse of the civil services. Second, the nature of the internet means that it holds a certain level of anonymity, even if we wanted to give you the number we couldn't track it down and verify it. Third, if your photo is on the internet than it is no longer entirely your property, thus them using it is unlikely to be illegal. There are some paths you can go to protect your photo through copy right but even that holds limitations assuming you even went through the proper channels for that (which you probably didn't). Basically, your a petty idiot that needs to learn how the internet works.
