Re: [O] [org-contacts] How to show avatar image on org headings?

[John Kitchin]

there are a couple of typos in your code, and the regexp doesn't seem to match the property you want for some reason. 

This seems to do what you want.

#+begin_src emacs-lisp

(defun org-contacts-icon-property-image-overlay (&optional limit)

  (when (re-search-forward org-heading-regexp limit t)

    (let ((beg (match-beginning 0))

          (end (match-end 0))

          (image-file (org-entry-get nil "ICON"))

  org-contacts-icon-property-image

  org-contacts-icon-property-image-overlay)

      (when (and (not (ov-at beg)) (file-exists-p image-file))

        (setq org-contacts-icon-property-image (create-image (expand-file-name image-file)

     'imagemagick nil :width 100))

        (setq org-contacts-icon-property-image-overlay (make-overlay beg (+ 1 beg)))

(overlay-put org-contacts-icon-property-image-overlay 'before-string (propertize " "

                    'display org-contacts-icon-property-image))

        (overlay-put org-contacts-icon-property-image-overlay 'org-image-overlay t)

        (overlay-put org-contacts-icon-property-image-overlay 'modification-hooks

                     (list 'org-display-inline-remove-overlay))))))

(font-lock-add-keywords

 nil

 '((org-contacts-icon-property-image-overlay (0 'font-lock-keyword-face t)))

 t)

#+END_SRC
