The default action is that of a timed slideshow.
To view this, just sit back and relax - the images will change every ten seconds automatically.
If you want to manually choose when to look at a new slide, simply click on
the previous and next arrows to the left and right of the image.
If you would like to select which images to view, click the phrase 'thumbnail scroller (click to open/close)' in the gray bar and when the
thumbnail scroller opens click on the thumbnail of image you wish to view. To close the 'thumnail scroller', simply click on the gray bar again.
