When I clicked on a few pictures, they expanded, which I expected. Later (in Berlin) I clicked on a picture and got a slideshow. I much prefer seeing all the pictures and clicking on the ones I want to zoom in on. It is indeed a great interface. My vote is a "play slideshow" button; otherwise, make zooming in on the pic the behavior when a pic is clicked.
