You can view a slideshow of all or a subset of your photos by using the Slideshow feature of the Sidekick Camera:
Decide if you want to include all your photos in the Sidekick slideshow or just a subset. If you want to use a subset, select all the photos that you want to include. You can select photos across albums.
The Slideshow dialog box appears, giving you all your slideshow options.
Select how long you want each photo to display from the pop-up menu (1/4, 1/2, 1, 2, or 5 seconds).
To repeat the slideshow after all the photos have displayed, select the Loop Slideshow check box.
If you haven't selected a subset of photos, the Show all photos option is selected for you. If you have selected photos, the Show checked photos only option is selected.
To have background music in your show, select a ringtone from the ringtone selector. Be sure to check out the songs in the "Moods" category. Read more about recording a ringtone in Record a New Ringtone.
