Hi Klaus,

I found the function very useful so I expanded it a little to have more
flexible image file names. First, I use the base name of the file in the
current buffer as a prefix to the image file name. Then I added an integer
buffer-local variable to be the image file name's suffix (preceded by an
underscore) which is incremented every time new image is pasted:

   #+begin_src emacs-lisp
     (defvar org-clipboard-image-suffix 0)
     (make-variable-buffer-local 'org-clipboard-image-suffix)
     (setq-default org-clipboard-image-suffix 0)

     (defun org-insert-clipboard-image ()
       (interactive)
       (incf org-clipboard-image-suffix)
       (let* ((image-file
               (concat (file-name-base (buffer-file-name))
                       "_"
                       (format "%d" org-clipboard-image-suffix)
                       ".png"))
              (exit-status
               (call-process "convert" nil nil nil
                             "clipboard:" image-file)))
         (org-insert-link nil (concat "file:" image-file) "")))
     #+end_src

It would be very convenient if there were a way to determine if the
clipboard contains an image, then use defadvice to call this function with,
say, org-yank. Unfortunately I couldn't find any emacs functions to query
properties of the content of the (Windows) clipboard. I only see
w32-get-clipboard-data which returns only text.

Regards,
Alex
