Yes, someone can do black magic on you with using your photo. Long time ago, before cameras existed, people did black magic using things like voodoo dolls. They had to imagine the person they wanted to harm, or sometimes they needed to see the person in real life to cast a spell, especially if they didn’t know their name.

Later, when paintings were made, sorcerers used them instead of seeing the person directly. Then, with the invention of cameras, it became even easier. Now, instead of meeting someone or using a voodoo doll, black magic can be done using just a photo, as it is the exact image of that specific person and it holds a connection with that person.
