I cant see your link, but what I think your trying to do is in the movies. You can make several different movies (ex. one default slideshow, one just panos, one just still images) then in your tour skin you can make a dropdown box to select between the different movies.
First make a button, then in the actions tab (next to properties tab) select movie, play/pause, the hit the + button. This will bring up a box to choose the movie you want the button to play.
