The Navigation Control
You can use the Navigation Control to pan the image or map in the Image window, to switch between viewing an image or viewing a road map, and to view additional images of the same geographic area you are currently viewing.
The Navigation Control contains the following:
- Navigation Compass (indicates image orientation, also used for panning)
- Pictometry button (to view the current image)
- Road Map button (the view the map)
- Next and Previous arrows (to view similar images) 
It also indicates the total number of images available for the geographic area shown in the Image window (x of y, where x is the current image and y is the total number available.)
