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

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

Nick, your code worked! My example image was small and I could change 
the size by altering the width variable. The same image in a regular org 
file is huge.

That means something is wrong with my org-mode install? I have not 
changed or done anything to org-mode that came with the compiled emacs 
24.3 version. Any  tests I can do?

Thank you - this process has already taught me a lot.
