images may specify a viewport by adding visible locations . the visible parameter instructs the google static maps api service to construct a map such that the specified locations remain visible ( this parameter may be combined with existing markers or paths to define a visible region as well ) . defining a viewport in this manner obviates the need to specify an exact zoom level .
