Prince William and Kate release photo of their daughter Charlotte for her sixth birthday

The photo of Princess Charlotte was taken by her mother, Catherine, Duchess of Cambridge.

London (CNN)Prince William and Catherine, Duchess of Cambridge on Saturday released a new photograph of their daughter, Princess Charlotte, to mark her sixth birthday.

The photo shows Charlotte in a blue floral collared dress, buttoned down the front. She is looking directly at the photographer, identified by Kensington Palace as her mother Catherine, the Duchess of Cambridge.
According to Kensington Palace, the photo was taken this weekend in Norfolk, England, ahead of Charlotte's birthday on May 2.
    Charlotte is fourth in line to the British throne, one place after her older brother, George, who will turn 8 years old in July.
      The Cambridges will not post anything on social media over the weekend in solidarity with an online boycott by England's professional football clubs aimed at urging tech giants to tackle racist and sexist abuse on their platforms. William said in a Twitter post that he will join the boycott given his position as president of the Football Association.
        But the couple still released the new image of Charlotte to media, as they have traditionally done on their children's birthdays.
