The article at the link below says that Getty Images is allowing freer access to its images by others. It says that it will do this by adding credit information via an embed code. This will make it clear where the image is from, and allow them to gather info about where it is posted, etc. It also allows them, if things change in the future, to remove such access.

For a small-scale Wordpress blog with no photo budget, this looks an awful lot like free stock imagery.
It's a real risk for the company, since it's easy to screenshot the new versions if you want to snag an unlicensed version. But according to Craig Peters..." The rest is at the link.
