Navigate with the Previous/Next buttons or arrow keys, or play the slideshow.
Note: the navigation keys and slideshow bypass the folder "group pictures"; click to view it.
Some pictures can be enlarged to show details: click the 1:1 icon and drag with the mouse if the picture extends outside the screen.
There is a music track of clips from 50's and 60's hits. Click the music note icon to bring up the music control bar. Click the icon again to close the control bar; the music still plays when the control bar is closed.
