After choosing an Album to view (by clicking on the desired one) the slideshow will begin. You will see thumbnails along the bottom and the viewer will display a larger version of the image above. You can view a larger thumbnail by hovering the mouse over the thumbnail image.

To return to the Table of Contents click the image in the bottom left corner.
The navigation controls on the left and right side of the thumbnail strip control pausing/resuming the slideshow and moving through the images manually.

To open an image in a separate window click on it when the PhotoViewer displays the image.
