Those sentences were in two separate paragraphs, and while not unambiguous, it's pretty safe to say that the first sentence was intended to relate to the photo above.
Nope. Every single photo had the description above it, including that one. "A more head-on view." Nor is the "head-on" photo random at all.
The "guy holding iPad awkwardly" photo only seems random if you don't recognize it, though. It was (apparently) the model for the "in use" diagram Apple put in their design patent. http://www.google.com/patents/USD504889
You're being a slave to patterns. By my reading it seems at least as likely that a mistake was made when the attachments were added to the text.
The existence of the paragraph break makes it fairly clear (to my reading) that the "it's random enough" paragraph was commentary associated with what had just come.
