Add sound to photo album?

Like many others, I am working with the photo album tutorial found at http://www.kirupa.com/developer/mx/photogallery.htm. Although I’ve gotten it to work fine, I am now trying to expand on it and I am a Flash novice so I need help. Specifically:

  1. I would like to loop a sound clip behind the photos and I would love it if the sound could fade after the last photo

  2. Is there a way to keep the <PREV and NEXT> controls but have the photos advance automatically if the person doesn’t click either of them? In other words, could the photos advance like a slide show but if someone wanted to zip through them they have the buttons to use.

  3. Bonus functionality: A pause button? In case someone finds a photo they want to look at?

Thanks for any help you all can offer.
