Augment CS3 PhotoGallery template to load from external directory

Hi people! I was wondering if you all could help me out. I’m not real well versed in Flash, just enough to get myself in trouble. I need to make a photogallery that has a specific skin over it for a web site for work. I found the template photogallery in Flash CS3 and it works fine but I was wondering if I can augment it so that the images are loaded from an external directory. Or would it just be easier to start from scratch and build something very simple. All I need is something that is a slide show that someone can resize and load images into a directory and the Flash calls the images. Don’t even necessarily need buttons, it can auto run.
