Kensington Palace posts birthday photo of Prince Louis, taken by Catherine

Britain's Prince William and his wife, Catherine, thanked the public for their messages sent to mark the sixth birthday of their youngest son, Louis, on Tuesday.

It's the first image by the Princess of Wales the palace has distributed since news organizations withdrew a photo edited by Catherine over concerns about digital manipulation.

British media reported that the image, which showed the beaming prince in a plaid shirt, had not been edited.

Louis is the youngest of their three children, with George, aged 10, and Charlotte due to celebrate her ninth birthday next month.
