Hi Guys,
I've placed this code on my ATO>HTML/CSS Inserts header section to actually provide thumbnails whenever I share content to social networks, unfortunately it seems to not work.
<link rel="image_src" href="http://www.seotaoist.com/wp-content/uploads/2010/05/SEOTaoist-Image-Source.png"/>
Did I place it on the wrong section?
Thanks!
