lay out two photos

Enlarge the footer's text box. Drag the top handle up to reveal the footer text.

Drag the upper-left handle of the top photo outwards to enlarge the photo without running into the caption text box.

You need to open up the text box to show all of the large caption. But the other caption is in the way.

Layouts vary with the orientation of the photos involved. You've seen the layout for two landscape photos. Here are the other two-photo combinations.

If you just want to change the order in which the photos appear, however, it's better to return to Step 2 of the wizard and rearrange them there.

In Step 2, drag a photo to change the order. The yellow bar previews the new location.
