Photosynth is an application that lets you stitch together your standard photos into a 3-D/panoramic style - great for showing off your listings!
Before you start, there are few things I want to point out ... first, anything you upload will be public - meaning that yes, anyone can see it. Usually, this is what we want as Realtors, so not a big deal. You will need to be running XP or Vista to use the app, plus there is a browser plug-in that you will need to download for viewing purposes.
