I run a news website and I write about entertainment. Things are going well, I have 4-5k daily visitors (and growing) and I just applied for adsense last night. For now I'm using pictures from Pixabay and advanced Google searches. Pictures free from any copyrights whatsoever. But as time goes by I definitely want to be able to use copyrighted pictures. Especially the amount of pictures with celebrities in them are very limited without copyrights. I've done some research but I can't really discover how to do this. Of course I do want to pay for it so I am able to commercially use them as I please. But where can I actually buy? And what about Adsense, how will they know that in fact I paid for it and will not ban my account? I would be thankful for bloggers out there with some experience being able to help me out.
