During the eight-day public tour, the prince and princess visited Jamaica, Belize and the Bahamas, all three former British colonies and today part of the British Commonwealth.
A picture shows Prince William and Kate visiting children through a metal fence.
In another photo, the couple stands up in a classic Landrover wearing shiny white clothing, the same type of vehicle that Queen Elizabeth used when she inspected troops in Jamaica in the 60s.
Although Prince William gave a speech during the trip in which he expressed grief over his ancestors' part in the slave trade in the area, criticism has hailed.
In the British media, the appearance has been called, among other things, tone deaf, to bring to mind the 30s and that the prince and princess should look like "relics from a bygone era".
New statement from the prince
James Savage, editor-in-chief of The Local, says the images look bad in light of today's debate climate and discussions about racism, old injustices and slavery.
According to British media, Prince William is upset about how the trip has been described afterwards.
After a crisis meeting with his advisers, he is said to have expressed that all countries the couple visited "are free and supported in the decisions they choose to make for themselves".
