Hi all,

Here's a little hack that I use to make my life easier:

(require 'async)
(eval-when-compile
  (require 'cl))
(defun org-store-image (link basedir)
  (async-start
   `(lambda() (shell-command
          ,(format "wget \"%s\" -P \"%s\""
                   link
                   (expand-file-name basedir))))
   (lexical-let ((cur-buf (current-buffer)))
     (lambda(x)
       (with-current-buffer cur-buf
         (org-display-inline-images))))))

(defun org-store-image-clipboard (link)
  "Save image at address LINK to current directory's subdirectory DIR.
DIR is the name of the current level 0 heading."
  (interactive (list (current-kill 0)))
  (let ((filename (car (last (split-string link "/"))))
        (dir (save-excursion
               (org-up-heading-all (1- (org-current-level)))
               (substring-no-properties
                (org-get-heading)))))
    (if (null (image-type-from-file-name filename))
        (message "not an image URL")
      (unless (file-exists-p (expand-file-name filename dir))
        (org-store-image link dir))
      (insert (format "[[./%s/%s]]" dir filename))
      (org-display-inline-images))))

(setcdr (assoc "^\\(https?\\|ftp\\|file\\|nfs\\)://" dnd-protocol-alist) 'dnd-org-insert)

(defun dnd-org-insert (uri action)
  (org-store-image-clipboard uri))

When it's a plain image, I can just drag it from the browser to org-mode. 
It will be downloaded in async to a subdirectory of the current directory and the link will be inserted 
at point. 
For stubborn images that are links I can right click to copy image location and call
`org-store-image-clipboard' interactively.

I hope it's useful to someone and that I'm not re-implementing standard functionality.
