Hi, I am starting my own site, however my concern is sourcing photos for the site. Can I get sued if I use other people's images on my website? What about if I edit them so they look slightly different? For example, if you look at The Daily Currant website (I can't post links) there are several photos that they obviously did not take themselves, such as photos of Obama and other prominent people. How can I use these types of photos without getting into legal trouble? Thanks!
