Generally use the viewer if it pops up as well, and usually will view all the pics. As with Madiosi, I had never considered that any view stats might be affected.When you click the first one a kind of viewer opens, and then you can scroll to view the others at a reasonable size. Then you can choose to view them in full size, if you wish, but often it's not much bigger.
I suspect a lot of people just do that, as do I a lot of the time, and then maybe it looks as though only the one image has been viewed?
