We design our interface with the last photo on the queue to say “LAST PHOTO”.  Normally, 1.jpg will have “TAKING PHOTO 1”, 2.jpg will have “TAKING PHOTO 3”, 3.jpg will have “TAKING PHOTO 3” and 4.jpg will have “LAST PHOTO”.  This is ideal for 4 photos layout.  If you’re doing 3 photos layout, the batch file will rename 3.jpg with _last_photo.jpg to have “LAST PHOTO”.

To revert back to 4 photos layout, double click on the 4_photos_layout.bat
