I have used Panopress all the years now. Thankyou for a good WordPress plugin.
I am using the Panotour pro version 2.2 now and with that a possibillity to put the 360º sphecical pano in an iframe.
But what are exactly the advantages of using your panopress plugin vs the iframe solution?
compared with simple iframe, panopress can also add easy click-to-load preview images, panobox lightbox clone, html5 fullscreen support, as well as handle embeds of xml files and swf and qtvr .mov without any html file, you could rig all that up in an iframe too of course, bt panopress would give you an easier embed interface and consistent display with older legacy panos etc
next update of panopress will also have better support for various html5 and webgl panos etc, mousewheel zoom fixes and the like
