At that place, I find this code:
(add-to-list 'iimage-mode-image-regex-alist (cons (concat "\\[\\[file:\ 
\(~?" iimage-mode-image-filename-regex "\\)\\]") 1))
  (defun org-toggle-iimage-in-org () "display images in your org  
file" (interactive) (if (face-underline-p 'org-link) (set-face- 
underline-p 'org-link nil) (set-face-underline-p 'org-link t)) (iimage- 
mode))
I guess I could actually add the above code to org.el, so that the  
only thing to do for a user would be to turn on iimage-mode.
What is the purpose of toggling the underline property of the link face?
