You could loop the display of whatever the latest image is with one program and then wait for keyboard input with another to get the next picture. In any case, you need some sort of framebuffer program that can display something and quit while leaving the picture on the display. I think that fbi erases it.
If there is a loop in the framebuffer display program that, say, gets pics for a slideshow or some other thing that you don't want, you might have to find the source and gut that part of the thing. It gets harder if it is using a library that insists on doing things deeply inside itself that you don't want.
