Getty Images has a massive collection of photographs that it licenses for commercial use such as company reports and magazines.
A subset of these images is now being made available at no charge for non-commercial use in websites, blogs and social media.
Getty Images' embed facility automatically provides proper attribution and a link to the company's site for commercial licensing.
That could cause a problem in some situations, for example when a hosting provider offers a free site or blog in return for the exclusive right to display advertising on the pages.
"Images are the communication medium of today and imagery has become the world's most spoken language," said co-founder and CEO Jonathan Klein. "Whether via a blog, website or social media, everyone is a publisher and increasingly visually literate.
"Innovation and disruption are the foundation of Getty Images, and we are excited to open up our vast and growing image collection for easy, legal sharing in a new way that benefits our content contributors and partners, and advances our core mission to enable a more visually-rich world," he added.
