Yes, the use of the display property for such uses is somewhat odd: you have to use a (dummy) before-string (or after-string) property on an overlay and place the `display' property on that string. The dummy string should have length >= 1. Typically the code looks something like: (let ((ol (make-overlay start end))) ;; start can be equal to end if you want (overlay-put ol 'before-string (propertize " " 'display ))) See for instance the code of put-image.
