National Gallery of Art, Washington DC: “Free open access image downloads are now available directly from the object pages located on this website. More than 60,000 images are available for download, and we will continue to add more as they become available. Our open data program is a natural extension of the National Gallery’s mission: to welcome all people to explore and experience art, creativity, and our shared humanity. We aim to make as much data as possible available to as many people as possible, in support of research, teaching, and personal enrichment. We believe that increased access to factual data about works of art fuels knowledge, scholarship, and innovation, inspiring uses that transform the way we discover and understand the world of art. You can download the dataset of factual art object information for the 130,000+ artworks and artists in our collection from Github. We release this data under a Creative Commons 0 (CC0) license. This means that you can download the full dataset free of charge, and without seeking our permission.”
