Flash Gallery/Slideshow AS3 Help Needed

Hey everyone. Here is my slideshow file (unzip all files to make it work correctly)

I am working on a slideshow and I was wondering if I can get some help on some additions. Basically the slideshow is basic with no transitions. The buttons are being created based on the number of images in my folder.

I would love to have thumbnails of images instead of created buttons for the slideshow. Is there a way to create that. I would imagine it would be like the code for pulling in the large images but instead make that code be for the thumbnails? So basically instead of the created buttons on the left they would be thumbnails of the larger pictures...makes sense?

Also, would there be a way to animate these images through AS3? Right now they do nothing unless you click on the button, but I would love for them to fade into one another, and be able to continue fading even after a new button has been clicked. Make sense?

Any help would be extremely awesome and very useful!

The final outcome of this would be to have a slideshow where the thumbnails are aligned from left to right on the bottom of the screen with the larger images above it. The images would fade from one to another based on their name, and once you click on a thumb to go to another image they still continue to fade.

Maybe we can start off from one place and continue forward. Thanks!!!
