How do I change the size of a photo in Adobe Elements?

A simple question which probably has a simple answer:

When I open a photo in Adobe Elements it's bigger than the space on the screen and I have to click the magnifying glass icon to reduce it so I can see the entire image. Is there a way of change your preferences so that the photo always comes up a bit smaller so I don't have to keeping clicking the magnifying glass icon?
