I use KM's Display Text to display quasi Reference Book Things that are hard to remember. I use the palette - select what material I am looking for, the display box displays the info - and I copy and paste it or remember it and hit enter.
I was wondering if instead of display .png files in the box?
Or is there any other way to briefly display a picture - that is easily exit-able via hitting enter.
For what it's worth, your original prompt might be enhanced with a copy action that happens automatically. Of course you also may not want your clipboard cluttered up with too much stuff.
