Sizing Portrait Photos Same As Landscape

How do you guys deal with photos that are oriented vertically (portrait orientation) in your reports? Do you only include photos that are landscape?
Or… Do you use them but allow them to all be as wide as your landscape photos which makes them very tall and take up a lot of space on the page? Do you make them all smaller so the height is similar to the width of a landscape photo? Do you pre-size them before your bring them in to HG?
