#392......"LEWIS COLLINS"

Perplexed and a little confused

How long have the new box sets been available to buy now, three years, four, something like that, so why is it that i have only just realised that there are no gallery pictures for the episode Heroes or is it my blu ray copy. I thought the dvd and the blu ray included the same content so why have i found these images but yet they are not on mine. Could anyone help please.
