Re: [Orgmode] Re: Wow -- adding images to an org file

[address@hidden]

I very much like the idea of native inline image display in Org-mode but  can't seem to make it work.

Given a 6.36 snapshot or 6.36 release and these org file contents

* Test image
Test image
[[Screenshot.png]]


I hoped org would display that image after C-c C-x C-v. Rather Org-mode returns "No images to display inline".

I've tried different ways of linking that image, different image formats, relative vs complete paths, and my regular .emacs vs  a near empty one and always the same result. If I toggle iimage-mode the image displays fine per se but does not affect how Org-mode works.

Seems clear I am missing something simple. What?


Cheers,

Robert Cunningham
