Set NAVIGATION/Appearance to "Hidden". Or if you'd rather only show the navigation on rollover, set the same parameter to "Visible on Rollover."
Set NAVIGATION/Link Appearance to "Thumbnails", then if you are creating your own slideshow content, follow these instructions.
If you are using SlideShowPro Director, thumbnails will be created for you automatically.
This is modified through NAVIGATION/Thumbnail Link Size. First number is the width, second is the height. You can use these target values if creating your own thumbnails.
You can choose which of the embedded navigation buttons to show using the NAVIGATION/Buttons Appearance parameter. If you would like to swap out SlideShowPro's embedded buttons with your own, you can do so with ActionScript. Follow these instructions to do so.
