The National Gallery of Art, Washington
The National Gallery of Art, Washington, was founded as a gift to the nation from Andrew W. Mellon and serves as a center of visual art, education, and culture. The collection includes more than 150,000 paintings, sculptures, decorative arts, photographs, prints, and drawings.
The mission of the National Gallery of Art is “to serve the United States of America in a national role by preserving, collecting, exhibiting, and fostering the understanding of works of art, at the highest possible museum and scholarly standards.”  To that end, the National Gallery of Art began making its collection freely available online in March 2012, when it initiated its open-access policy. 
Contributions to Wikimedia Commons
In September of 2018, the National Gallery of Art began a partnership with the Wikimedia Foundation with the goal of donating the museum’s 53,000 open-access images of artworks to Wikimedia Commons. By the end of September 2019, nearly all of the intended 53,000 had been uploaded. Additional images are expected to be contributed each year. All images donated to Wikimedia Commons are made directly from the artworks by museum photographers and reviewed by a staff color scientist. Each primary file is embedded with descriptive metadata. These files are publication quality, up to 4,000 pixels on the long dimension. All images are dedicated Creative Commons 0 Universal License (CC0).
The files contributed to Wikimedia Commons are organized in the following category and subcategories:
