via which the slideshow can be started and halted. Automatically start slideshow
has the effect of automatically beginning the slideshow upon loading the page. In Slideshow speed,
you can enter a value in milliseconds, after which the images are to be switched.
In the lower area you can select the desired effect with which the images are to be switched.
The Duration of effect upon image change can also be set in milliseconds here.
