Kate and William - who had a photo with their children Prince George, Princess Charlotte and Prince Louis clapping for carers last year - chose their joint monogram which features a curly C, for Catherine, over a black W, for William, both written in calligraphy.
Prince Charles and Camilla's profile - which had a photo of the couple smiling in an official portrait released to mark Wales Week 2019 - chose to display the Prince of Wales's feathers. Meanwhile, the royal family's avatar changed from a photo of the Queen and Prince Philip at the Epsom Derby in 2016 to the Queen's coat of arms.
The royal family's website also updated its main page to an image of Philip against a black backdrop, with "The Duke of Edinburgh 1921 – 2021" written underneath his photo.
