Photographers who use 500px to distribute their work are now adjusting to two big changes. First, the platform is removing the option to upload or download photos with a Creative Commons license. On Saturday, it also shut down its stock photo platform 500px Marketplace, and replaced it with distribution partnerships with Visual China Group, which acquired 500px earlier this year, for users in China and Getty Images for the rest of the world.

The decision to close Marketplace was first announced at the end of May.
