The pictures include one showing four generations of the Royal family, with the future King in the arms of his mum Kate sitting next to dad William.
The Queen, Prince Philip, Prince Charles, his wife Camilla and Prince Harry were also pictured after attending the private ceremony at Chapel Royal at St James's Palace, London, on Wednesday.
Kate's parents Carole and Michael Middleton and her sister Pippa and brother James are also in the image.
Baby George, who is now three months old, has not been seen in public since his first appearance shortly after he was born.
Pictures were released when he was four-weeks-old, showing him sleeping in his mother's arms as the Cambridges sat in the garden of the Middleton family home near Bucklebury, Berkshire.
William and Kate have divulged small insights about life with their son since he was born. William said in an interview: "He's a little bit of a rascal."
