you mean the picture from this page? really?
It was a picture of a beach-party for their summer-fest world event. Actually the picture is somewhat reminiscent of the beach-parties from the late 60, or at least how they were portrayed in movies. For example, consider this
movie promo poster for "Surf Party". (point of reference the movie was released in 1964)
I think the image that they used accurately gave the impression of the ascended kicking back and relaxing in the hot, lazy days of summer.
