The British royal family has released photos of Prince William and family on a ski vacation in the French Alps. The pictures come from an agreement between the royals and photographers. It was set when William and his brother, Prince Harry, were children. Their mother, Princess Diana, was killed in a car crash when photographers were chasing her car in Paris. Reporters respect the family’s privacy in exchange for arranged meetings on special days. The images published Monday show William and his wife Kate with 2-year-old George and 10-month-old Charlotte enjoying the snow last week. Officials say it was their first holiday as a family of four and the first time either of the children had played in the snow.'' Two pictures show William and Kate at play in a snowball fight. The policy with the press meant the boys could have a relatively normal childhood. Kate and William have expressed the desire to give the same to their own children.
