Not many people know this, but if you take an image from a website and download it, then go to
https://images.google.com/ - you can drag the image from the website and drop it in the search box. It'll search the web for the same image. If you're surfing backpage, and you see a babe - odds are the pic has been used for multiple ads all over the country by some skank agency. If the pic is real, then it'll only bring up the ads for that girl. Check it out - very useful. (and dangerous too - be careful of where you put your face!)
