When posting link to my wordpress geekgirlscarrots.pl on Facebook, thumbnail images don't display at all.
I've put at header the following code:
<meta name="title" content="Geek Girls Carrots" /> <meta name="description" content="Visit our site! Come to our meetings!" /> <link rel="image_src" type="image/jpeg" href="http://geekgirlscarrots.pl/wp-content/uploads/2012/02/1GGC_for_web_logo.jpg"/>
but it doesn't work. If anyone could help me?
