He is talking trolling about embedded images that are server-side. Even if this is possible somehow (I doubt it) then the server will fetch the image using Tor network and our "genius" will see Tor exit node's IP address in his logs. His posts at the end sound hillarious. How can someone know about all this stuff and have completely wrong understanding even in the basics? Maybe he is a so called "white hat" who just finished 5 year training in computer security?
