Displaying static photo

Everytime I try to display a static photo- it defaults to the screen saver within a couple minutes-
I need to keep a static pic for duration of a seminar.
If having to use an app, are there basic, free ones (hesitate to say inexpensive) to simply a photo from a usb drive?
Please be specific if there is one, not a generic “use any photo display app”- I’m tired of hunting.
Real help would be most fully appreciated.


What projector are you using? Have you reached out to support?
