If Image is linked to another application that knows about crosshairs, it can control them. The bounding box is a representation of a rectangular chunk of the database. It can tell other applications about its position and size in order to compute statistical information about the data within the box or to limit the application only to data within the box.
Bounding boxes can be inclusive or exclusive.
