I'm facing this problem that when I include some LaTeX specific attributes for my image, then the image doesn't display inside org-mode (although it is displayed fine in my exported LaTeX PDF).
For example, if I include an image like this, the image stop showing inside org-mode:
#+ATTR_LATEX: :width 7cm
[[img/img2.png]]
However if I remove that LaTeX attribute, then it is displaying fine inside org-mode.
