Once your Photo Album presentation has been created, you may notice that the default Photo Album template is a white background with black text. And if this is what you exactly want — then you need not change a thing. But you can easily change the appearance of the slides by applying a Theme to your Photo Album presentation. You can of course do it outside the Photo Album presentation — in the normal way that you apply a Theme. But you can also apply a Theme right within the Photo Album dialog box.
