Information popups

I wish to add "hotspots" to various scenes which link to image URL's which

1) image pops up when the hotspot image is clicked
2) audio begins to play (and audio has option to be stopped by the viewer)
3) which returns to the same scene when the pop up image is again clicked.

I'm looking for a very simple bit of XML example to get started.

I do have questions, of course..
a) should the new image and audio URL be within a LAYER or WITHIN a SCENE (or something else)?

Thank you for any help you might be able to offer.

No replies at all? I do use the paid version. Could someone please say where I can get answers?

By the way - I figured an option modifying the VIDEO example...
