Photo Gallery question?

I have a question about the gallery tutorial that’s posted on http://www.kirupa.com/developer/mx/photogallery.htm

I’ve created a gallery which works fine. Now my question is, how could I customize it, let’s say instead of just going left and right, how can I specify each button to each image so it fades in and out when clicked???

I’ve used this command on one of the buttons which does load it properly but the fadein/out effect doesn’t work.

on (release) {
_root.photo.loadMovie( “folder/myimage.jpg”);
}

If anyone could help, I’d greatly appreciate it!
