This site was formerly called Your Paintings, and is now called Art UK, which is the new operating name of The Public Catalogue Foundation. This has been a project to document images and details of every painting (in oil, tempera or acrylic) in public ownership throughout the United Kingdom. In 2016, they are expanding the project to include watercolours, pastels, drawings and prints. In early 2017, they aim to add sculptures.
