AddThis does not officially support all of these parameters, as far as I can tell (I cannot find them all in one place in my documentation), so ideally you should just use the OpenGraph tags on the page where you are located. But anyway...
You need to specify it yourself, and not on the toolbar. You can even specify an image. If your buttons should come from AddThis and not specify them yourself, I'm not sure.
<div class="addthis_sharing_toolbox"> <a class="addthis_button_facebook" addthis:url="http://google.com/" addthis:title="Here a title" addthis:media="http://images.google.com/example.png" addthis:description="Here a cool description"> <i class="ico ico-facebook"></i> </a> <a class="addthis_button_twitter" addthis:url="http://google.com/" addthis:title="Here a title" addthis:media="http://images.google.com/example.png" addthis:description="Here a cool description"> <i class="ico ico-twitter"></i> </a> <a class="addthis_button_linkedin" addthis:url="http://google.com/" addthis:title="Here a title" addthis:media="http://images.google.com/example.png" addthis:description="Here a cool description"> <i class="ico ico-facebook"></i> </a> </div>
The AddThis documentation sucks, so I just ran into the right things and figured it out. Enjoy it!
