Can anyone tell me the functionality behind the panoramic views on this page?
I know it's javascript,
<a href="javascript:LoadVR1()" class="jk1">View 360&deg;</a>
but it requires some kind of plugin to work, and I don't know what that is.

Also, I don't know where and how the actual files behind it (VR1) are stored. Any clues as to where they are likely stored on the server?
