Judge a Site by its Image
Find out what a site is all about by looking at a random selection of the images hosted on its web pages. Even if you are somewhat familiar with the target site’s content, this can be an entertaining little exercise. You will almost surely find something you didn’t expect to see. All you have to do is use Google’s site: operator to target a domain in an image search.
