I’ve never used Instagram. Is there seriously no way to block a user? They definitely flubbed their design here. At the very least providing a setting which lets you disable automatic image previews for messages from strangers, and requiring an introductory comment, needs to be added. And blocking specific users is beyond crucial for ANY social platform. I’m also wondering, in this post you seem to believe that you were the intended recipient of the photo. Is there any reason to believe this wasn’t simply a ‘wrong number’?
