Photography platform 500px will no longer allow photographers to license their photos under a Creative Commons license, and is removing the functionality to search and download such images. The site also closed down its stock photo platform, 500px Marketplace yesterday, replacing it with distribution partnerships with Getty Images and Visual China Group.

Earlier this week, the site updated its contributor FAQ, explaining that the closure of 500px Marketplace, in favor of Getty Images and Visual China Group was “part of a strategic repositioning of 500px’s network of contributors and the licensable content they submit to 500px.”
