In a bold move – Getty Images has made several million of their stockphoto’s (which can cost from a £1,000 to purchase) free for editorial use with their new “embed” option.
The embed option includes attribution to Getty Images and to the photographer – which is fair enough as the Creative Commons Attribution license asks for something similar.
With the appropriate CSS, the embed scales nicely for mobile/responsive, through for WordPress users there is no option to set a “Featured Image”.
Perhaps that will come in time?
