It was founded for the project, completed between 2003 and 2012, of obtaining sufficient rights to enable the public to see images of all the approximately 210,000 oil paintings in public ownership in the United Kingdom. Originally the paintings were made accessible through a series of affordable book catalogues, mostly by county. Later the same images and information were placed on a website in partnership with the BBC, originally called "Your Paintings", hosted as part of the BBC website. The renaming in 2016 coincided with the transfer of the website to a stand-alone site. Works by some 40,000 painters held in over 3,000 collections are now on the website.
