Thor likes to take pictures. Tony got him a digital camera and taught him how to use it. When Thor returns to Asgard, he likes to show Sif and the Warriors Three pictures of modern New York (as well as other destinations.) When he returns to Midgard, he likes to show all the Avengers his photos of Asgard.
I like how they manage to make her look just like Lynda Carter. It looks like she's doing the iconic spin, it was actually exclusive to the TV-show, but I'm sure it appears here as well, this being based on the TV-show.
