How to add transitions to slideshow photos?

When you import photos, a slideshow will be created automatically. By default, no transition will be used. To add transitions to photos, mouse over the slideshow and click the Edit button. In the Slideshow window, select the photo you want to add a transition effect to and choose an effect from the Transition Effect option. You can also use Transition Duration option to set the duration of the selected transition.

Note: The Photo Duration decides how long a photo will be displayed. Change it if you want.
