I'm looking for some pics of dragons. I am writing a book and have a page on facebook called, The Dragon King Chronicles and am going to advertise my page but I would like to use a pic of a dragon for the profile pic and one for the cover pic. Anyone have their own pics that they own the rights to that I can either borrow for my page or purchase? I've asked several people but no one has answered me back yet.

I know people use google pics, but is that legal?

Thank you!
