Flash virtula tour

hey,
is there any way i can make a flash interface for my client to be able to upload there own photo sequency to come up with this virtual tour at — http://www.neustep.com/

Or should i do it manually (every project) with rendered 360 degree panoramas say every 3ft along the animation path ?
how does neustep do it?
Any advice on how to go about it will be appreciated.
