it is a little trick that I use to find thieves of my works, I've the Chrome extension in my browser called Reverse Image Search, so when I right click on any image it appear this option and it searches for that image on the web.
Thank you! I've reported them but I doubt anything will come from it. I never understand why they protect the people that steal. I've had facebook and twitter accounts created of people pretending to be me, using my photos and saying my real name. But they are protected when I report it. >__< I just don't get it.
