- emacs -Q
- insert this function:
(defun image-wipe-and-insert ()
  (interactive)
  (let ()
    (with-current-buffer (get-buffer-create "*an image area test buffer*")
      (switch-to-buffer (current-buffer))
      (erase-buffer)
      (insert-image (find-image '((:type png :file "/usr/share/emacs/24.4/etc/images/icons/hicolor/128x128/apps/emacs.png"
                     :map  '((rect . ((0 . 0) . (50 . 50))) anAreaID (:pointer hourglass :help-echo "You found an area!"))
                     ;; :relief -20
                     ;; :conversion laplace
                     :margin (0 . 0)
                     :pointer arrow)))))))

- M-x image-wipe-and-insert
- Point mouse into top left corner
- results:
  - change of pointer, but not to hourglass;
  - no help-echo message.
