Possibly Power Point; I think you can save a file in presentation mode that auto starts. As to whether it starts in full screen mode, I don't recall.
Edit: I just tested it . . . if you create a slide (one slide if only one photo) and save the presentation as a Power Point Show (.ppsx), it will go to full screen. I am using Office 365 and Windows 10. I don't know if the feature is in OpenOffice, but I suspect it is.
