Re: org-image-actual-width has no effect

[Claudius Mueller <claudius.mueller@gmail.com>]

I got it to work! Thanks to Nick's code pointing to org-mode as the 
culprit, I re-installed org on top of a fresh compile of emacs (24.3.1). 
Using the org version that came with the freshly compiled emacs, inline 
images did not scale. Installing the latest version of org (8.2.7c) and 
org-plus-contrib on top of the fresh emacs compile (via emacs packaging 
system) did the trick.

Thank you for your help!!!
