The Photo Viewer application is a straightforward photo-viewing application. The first screen shows thumbnails of each photo in the gallery. When you click those thumbnails, the selected image shows in the main part of the screen. The next screen is a different list view, which uses a component that simulates a carousel. If you press the Next and Previous buttons, the carousel rotates so that the selected image is centered. The final view is a slide show. The image shows full-screen, but if you hold the mouse over it, control bars appear that show the details. You can also pause the slide show, move to another image, or change back to other views.
