Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

     http://orgmode.org/manual/Feedback.html#Feedback

Your bug report will be posted to the Org-mode mailing list.
------------------------------------------------------------------------

With current org-babel it is not possible to set separate html
attributes for result block.

Simple case:

,----
| #+begin_src ditaa :file 123.png :cache yes
| ...
| #+end_src
| 
| #+results[f8f8...]:
| file:123.png
`----

Suppose, I want to add some html attributes to image:

,----
| #+begin_src ditaa :file 123.png :cache yes
| ...
| #+end_src
| 
| #+attr_html: alt="big image" width="100%"
| 
| #+results[f8f8...]:
| file:123.png
`----

But when I do C-c C-c on ditaa block, it inserts one more result block:

,----
| #+begin_src ditaa :file 123.png :cache yes
| ...
| #+end_src
| 
| #+results[f8f8...]:
| file:123.png
|
| #+attr_html: alt="big image" width="100%"
| 
| #+results[f8f8...]:
| file:123.png
`----

Because org-babel does not skip #+attr_ ... lines when searching results
block with `org-babel-where-is-src-block-result' function.

I've added skipping every #+attr_ line between #+end_src and #+results
blocks.

Patch is attached.
