You cannot at this time do a slideshow. That function is not active in this version. You can set it to one photo file and show one on your Intermission and Audio screens. Putting a photo on the Lyrics and Video screens would not work because it wouldn't be seen as it would be covered up by the lyrics and videos.
The Marquee set-up is not in the Show Display except to set its location and whether it is hidden on a particular screen. To change what is showing on the Marquee, click on the Marquee button on the main screen. Then you can add or change whatever you want it to say.
