live refresh of inline images with org-display-inline-images

Question

Recently I've noticed the function I had been using to do refresh had stopped working and I had to change to a simpler call.

I used to have:

(defun k/org-babel-refresh-inline-images ()
  (org-display-inline-images nil t))

(add-hook 'org-babel-after-execute-hook 'k/org-babel-refresh-inline-images)

which had been recommended on the mailing list.

However, that stopped working and I've found:

 (add-hook 'org-babel-after-execute-hook 'org-display-inline-images)

to work, but I'm not sure why the original stopped working. Presumably, the original version might be more efficient if it worked. Why doesn't it, and why was the original preferred?

Answer 1

This works for me on Emacs 24.4.1 with OS X using the included org-mode (note the use of redisplay vs. display).

(defun shk-fix-inline-images ()
  (when org-inline-image-overlays
    (org-redisplay-inline-images)))

(after-loading 'org
  (add-hook 'org-babel-after-execute-hook 'shk-fix-inline-images))

Answer 2

For me, only the snippet below worked:

;; Always redisplay inline images after executing SRC block
(eval-after-load 'org
  (add-hook 'org-babel-after-execute-hook 'org-redisplay-inline-images))

For details, in my case, org-inline-image-overlays was behaving in the opposite manner as it should in the "when" statement: it was being set to a value only when an overlay was being shown. Maybe due to changes in later versions?
