Although they appear very similar, the difference that is most obvious from the picture is the beak. Kings have the longest beaks in the penguin world, while emperors have shorter beaks that have a more pronounced downward curve,.
When this penguinarium opened at the Detroit Zoo in 1968 it was the first zoo building in the world designed entirely for penguins, and housed king, macaroni and rockhopper penguins. It was replaced in 2016 by the $21 million Polk Penguin Conservation Center, which is now the largest penguinarium in the world. Gentoo and chinstrap penguins were added to the new habitat. There's a good picture of the new exhibit here on ZooChat.
