body: Google is indexing other people's websites across the planet. To some extents, the images on Google images search are also taken from websites contents. And all of that happens without owner's consent or any sort of agreement. (I saw some of my website content on google search image). So my questions is: 
  
  
  1. To which extent someone can use other people's web content?
  2. What rules are regulating search engines?
  
  
  
title: Is Google legal?
