Re: Help getting started...

Without getting heavy with actionscript, you can put all the pictures on one timeline, a new keyframe 120 frames apart with a different pic on each one. Each picture will be show for 4 seconds at 30 fps. On the layer above it, have a black rectangle (movie symbol) the size of the document with a keframe 10 frames before the next image, one above the new image, and one 10 frames after. Motion tween the black rectangle between those 3 keyframes, and then turn the Alpha on the first and last (of those three) keyframes to 0%.

The result will be a black fade in and fade out of your slide show, but it will not be interactive. It will be a movie slideshow. And a dirty way to handle the sound is to throw it onto a new layer itself, one keyframe at the beginning and regular keyframes that will span the length of the show. Another down side is that it will make editing annoying later to change timing.
