It's a cockpit error: you should use 'pointer', not ':pointer' in the
first instance. IOW, this works for me (note the underlined part):
(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)))))))
(Yes, it's confusing to have ':pointer' on the top level and 'pointer'
inside the value for ':map'. But the manual correctly says 'pointer'
in the latter case, so at least the documentation is consistent with
the code.)

Thanks a lot, indeed I missed that point!
Now, however, I have a follow-up problem (which kind-of nearly fits
the subject line): I was actually trying to get more than one of these
hotspots onto the image, something like this:
(defun image-wipe-and-insert-two-maps ()
(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!"))
((rect . ((51 . 51) . (100 . 100))) aSecondAreaID (pointer hand help-echo "You found another area!")))
;; :relief -20
;; :conversion laplace
:margin (0 . 0)
:pointer arrow)))))))
I thought this would be in accordance to the info node, where it says:
``An image map is an alist where each element has the format `(AREA ID
PLIST)'."
But my attempt to insert two of those elements leads to no :map
properties being shown for the image.
They are there, though:
(with-current-buffer "*an image area test buffer*"
(pp (text-properties-at (point-min)) (current-buffer)))
gives me:
(rear-nonsticky
(display)
display
(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!"))
((rect
(51 . 51)
100 . 100)
aSecondAreaID
(pointer hand help-echo "You found another area!")))
:margin
(0 . 0)
:pointer arrow))

This variant works as you expect:
(defun image-wipe-and-insert-two-maps ()
(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 (list
((rect . ((0 . 0) . (50 . 50))) anAreaID (pointer hourglass help-echo "You found an area!"))
((rect . ((51 . 51) . (100 . 100))) aSecondAreaID (pointer hand help-echo "You found another area!")))
;; :relief -20
;; :conversion laplace
:margin (0 . 0)
:pointer arrow)))))))
(Figuring out why you need that explicit call to 'list' is left as an
exercise ;-)

So now that we agree there's no bug here, I can close the bug report.
Thanks.
