AddThis

Sharing Multiple DOMs of a page

Hi,
I am trying to integrate Addthis into a small project I am working on.
So I want share multiple elements of a page separately, like each photo, and videos and other
elements on the page.

Is there a way I can tell add this tag to pick the content of a div or span ?
The issue is with facebook sharing precisely.


Here is the tag I am using :

<a class="addthis_button" href="http://www.addthis.com/bookmark.php?v=250&amp;pubid=" addthis:url="some url" addthis:title="About" addthis:description="Check this out: "><img src="http://s7.addthis.com/static/btn/v2/lg-share-en.gif" width="125" height="16" alt="Bookmark and Share" style="border:0"/></a>


Thnx in Advance.
