Instructions
Open the SD card slot cover along the right edge of the unit.

Press the "Power" button to start your Nintendo DSi.
Tap the "Camera" icon on the bottom screen using your stylus.
Tap the "Album" option. A list of photos saved to the SD card will appear.
Scroll through the photos and tap on one to view it at full size.
