Hi, Ive already asked on this theme, so Im sory for asking again

I would like to move between two VRs just by clicking on some sign. Something like on this website http://www.virtualgolf.cz/golf-club-...n/jamka02.html - I mean this sign http://spangler.cz/temp/re/sign.jpg

Someone told me that this is possible in Pano2QTVR software, is it true ? Or is there any easy way to make it (for free will be great) ?

Thanks to all!
