Oops, sorry very late reply. But thank you for the helpful ideas. Helpful and useful and not what I was looking for, which is an answer in itself, I guess the simple magic parameter just isn't there. Yes I was thinking of youtube videos where you can embed a whole bunch in a page and they only load ...

Seconded

Is there an easy way to stop swf panos loading until the user activates them? I'd like to be able to put several onto a page but not have them all start downloading when the page is loaded. Just something so the panorama only starts downloading when clicked on by the user.
Thanks

Currently you need Flash to build such a thing. With Pano2VR 2.2 it will be possible to do this entirely with the skin editor.
The example you downloaded is for Flash 8 so you need to export the panorama as Flash 8 file to use it with this code.

So can we now do this with the 2.2 beta?

Not now, but I will add it with the next version. Meanwhiles you can use the Adobe Flash version detection kit http://www.adobe.com/products/flashplayer/download/detection_kit/ Pushy question but have you now integrated an autoupdate system now the next version is out? The main thing that tempts me...
