The interface is no-frills and easy to grasp in a single sitting. I was able to put together a 7 image tour with multiple links in under 30 minutes, and that was the first time using the program. See it here: http://www.add360.com/archangels/virtual_tours/tour-quicktime/image2.mov
The software offers links to internal images, external webpages and tooltips.
