If you are not comfortable with actionscript, you can just make each slide a movieclip and have it animate into view using timeline tweens. If you can deal with actionscript, then you can convert the slides to movieclips and use the Tween class to make them gradually appear as you enter each frame.
Thanks for your answer.
Will either/both of your suggestions allow my original .FLA file to continue to run in the original 5 frame layout that I've built? I was looking around the help files and it looks like anything I try is going to force me to use multiple frames to achieve my desired effect....
Yes, you can retain the 5 frame layout in either case. In the first case you create each image as a movieclip that has the image transition into view using a timeline tween. When you place these movieclips in the main timeline they will take up the same one frame, but will animate in that frame since they are movieclip in themselves.
