Pitchero have changed the way the photos are initially displayed so that only a square section of each photo is shown. This means that there are missing parts of heads and faces!
This is what you need to do:
(1) When you open the webpage click on the first picture. (The group) This now shows the square thumbnail photos.
(2) Now click on the first square picture showing a guy with a drink in his hand.
(3) Carefully move the pointer to find the small blue arrow at the right and use this to view the other photos. (Not the large white arrow that is part of the advert!)
