Unsplash has just released "the most complete high-quality open image dataset ever": an open-source collection of over 2 million images captured by over 200,000 photographers, now available to download in bulk for free.
The Smithsonian just made a public domain contribution that it's calling "unprecedented in both depth and breadth." In one fell swoop, the institution is adding over 2.8 million images to an online platform called Open Access, where you can browse and download images for free.
Last week SpaceX posted its photos to Flickr and released them to the public domain. Unfortunately for the company, Flickr didn't have any public domain designation they could use, so even though SpaceX founder Elon Musk said the photos were public domain, the images were shared under a Creative Commons license that required attribution.
That has now changed. Flickr announced yesterday that it has created two new options for members in the copyright dropdown panel: public domain and CC0, which allows users to release content to the public domain.
