One of the simplest would be for long images to be used at the bottom of the screen. A single image with that functionality would be very useful.
Edit: Also, an image only needs to be made once across the board. A sword image could be fit on the bottom of the screen or on the side, a single arrow could point in all directions, you could even link them to a Deadly Strike or something to that effect. When you press the button, the image flips so a player knows it’s been pressed.
