Getty Images, the world's largest photo agency, has made vast swathes of its library free to use, in an effort to combat piracy.
Millions of images - including famous shots of Marilyn Monroe and Barack Obama - will now be available without cost to blogs and social media sites.
The photos will be "framed" with a code that links back to Getty's website.
