You need to be educated on chain tension! It is not good to have your chain as tight as humanly possible. It will cause more friction (ie mean you have to put more work in to maintain speed) and it will wear out your drive chain faster. Ideally I'd say you want about a half inch of play. This'd give you the optimum balance of tension while keeping friction down. That bike looks pretty much spot on.
