A previously unknown painting by 17th Century master Van Dyck has been identified after being spotted online.
The portrait was previously thought to have been a copy, and was in storage at the Bowes Museum in County Durham.
But it was photographed for a project to put all of the UK's oil paintings on the BBC Your Paintings website, where it was spotted by an art historian.
