Seems like we have established that it's more of a case of miscommunication since what EC said is "that's all you have". If one is objective, you can think that he's expecting more from the photogs, maybe because he usually shows a lot of pictures? Of course, if you think of it sarcastically, it will have opposite meaning. Heck, if you put a ! or ? behind that short sentence, the meaning is totally different.
As i have said in my post, i truly believe that EC probably just want to show his pics to point out any mistakes that he may have made. In any case, if in doubt, ask or clarify. That's what everyone should do right? :P
