30 ;; images instead of `insert-image', so don't delete such overlays
31 ;; sloppily.  Here is a sample code to show icons in the buffer.
32 ;;
33 ;;(let (image icon from to overlay)
34 ;;  ;; The function `find-image' will look for an image first on `load-path'
35 ;;  ;; and then in `data-directory'.

38 ;;                                      :ascent 'center)))))
39 ;;  ;; `propertize' is a convenient function in such a case.
40 ;;  ;; String must have one or more length to wear an image.

59 ;; not yet support images.  It is a pity that neither icons nor tool-
