This is the example interface for John Hendrikx' Fastview picture viewer.
It shows the /M multiple list (try to multiselect files from the ASL file requester :-), demonstrates the SCREENMODE and PUBSCREEN popup buttons, several preclicked switches and integers.
The "Delay" integer is limited to 60. This is done via the template with DELAY/N (min=0 max=60 def=30).
