In Site Scan, within 2D view, create a way to select a group of photos by circling them. Once selected then have the option to expand them to full size and have the ability to scroll through them in the order they were taken. Also being able to select and download all or some of the photos. When you close the expanded window you would go right back to the zoomed level you were previously at so that you don't forget where you were inspecting.
