There are several ways to add photos to your slide show.

When you add photos, a default motion template (see Using motion templates) will be applied based on your preferences.

Once your photos have been added to your document, you can reorder them or sort them by dragging and dropping (see Editing the order of photos) or by using the photo organizer (see Using the photo organizer).

Photo to Movie will automatically try to orient the photos upright if orientation information is present in the photo file. If it is not present and the photo is not oriented properly, you will have to manually rotate and/or flip the photo (see Rotating and flipping photos).
