Hi Marcelo,

Thanks for the suggestion.  It is currently possible to fold source
blocks (just TAB while at the beginning of the #+begin_src line), and in
addition it is possible to automatically fold all source blocks when
opening an Org-mode file by adding the following to your file header
lines

#+STARTUP: hideblocks

As for automatically hiding blocks, there are a couple of issues which
make me warry of going down that path.
1) it would be complicated
2) it could prove annoying in the (in my experience common) case when
   you *do* want to see and edit the innards of a source-code block
3) the results of a source code block are in no way constrained to be
   located after the body of the block.  In cases where they are not
   located near each other the body would be invisible (which is not
   desirable) and when viewing the results there would be no way to tell
   if there is or isn't a source-block hidden beneath it

is it possible that the current folding behavior is sufficient?

The following allows viewing images inline in Org-mode files using
iimage-mode.  This may be helpful.

--8<---------------cut here---------------start------------->8---
;; iimage
(require 'iimage)
(setq iimage-mode-image-search-path (expand-file-name "~/"))
;;Match org file: links
(add-to-list 'iimage-mode-image-regex-alist
             (cons (concat "\\[\\[file:\\(~?" iimage-mode-image-filename-regex
                           "\\)\\]")  1))
(defun org-toggle-iimage-in-org ()
  (interactive)
  (if (face-underline-p 'org-link)
      (set-face-underline-p 'org-link nil)
      (set-face-underline-p 'org-link t))
  (iimage-mode))
--8<---------------cut here---------------end--------------->8---

I see the point of your suggestions, and I don't deny that folded source
blocks would be slick, I'm just not sure that they would be worth the
additional effort/complexity -- however anyone is encouraged to disagree
with me :).

Thanks -- Eric
