I recently came across many sites showing a Google streetview in panoramic mode, like this one: http://jackiedu.com/aprg/list/mypropdet.aspx?sid=100081&pid=706831, in the right bottom you will see it.
How was that generated? Google? or by the website itself?
Thanks.
Javascript API for google maps has a panoramic mode. http://code.google.com/apis/maps/documentation/javascript/reference.html#StreetViewPanorama
