TIPS FOR NAVIGATING SLIDESHOWS:
1. The slideshow plays automatically and loops continuously.
2. Clicking anywhere on any image in the thumbnail bar stops the automated slideshow.
3. Clicking the large right or left arrows allows you to manually move forward and backward through the slides.
4. Clicking the small right or left arrows allows you to scroll forward and backward through the thumbnails.
5. Clicking on a thumbnail brings that slide up for view.
6. Clicking on your browser’s refresh button restarts the automated slideshow from the beginning.
