We need several items: buttons for going to the next and previous slide, main menu, and a button for the automatic slideshow. Further we need buttons for thumbnails. A complete picture of a frame is shown in the figure.
Thumbnail buttons: We create an invisible button, which only shows the area for the mouse but is otherwise empty. Instances of this button are used for opening slides by clicking on the thumbnail images. You do not have to name them but I did it for clarity to know which button belongs to which nailholder. Then we need movieclips to hold our images:
for showing individual slides (slideHolder) and for the thumbnails (nailHolder).
You have to name all of them. Next we need dynamic textboxes for the slide descriptions and instructions.
