That depends on your dogs level of training. At a glance I see a number of factors and concepts that you could teach. If you break down the concepts you will start to see possible setups. So the factors in that pic are cover, shadows, slots, long water entry, cheating singles, elementary channel swims, multiples down the shore, pushing out of water on the far shore, angle entries, and contrary marks (if you choose to do them, I don't like them). I'm sure some others may chime in and see something I don't but think about those factors while you look at those pictures and some marks and blinds will start to emerge. Just remember, train, don't test.
