Problem with displaying images on Facebook from my wordpress

Question

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?

Answer 1

I think you're looking for Facebook Open Graph Meta Tags specifically this one

<meta property="og:image" content="http://geekgirlscarrots.pl/wp-content/uploads/2012/02/1GGC_for_web_logo.jpg"/>

The linked image image needs to be 50 x 50 px.

It should be accompanied with these other og: tags

<meta property="og:title" content="Facebook Open Graph META Tags"/>
<meta property="og:url" content="http://my.url.html"/>
<meta property="og:site_name" content="Webmaster Blog"/>
<meta property="og:type" content="blog"/>

Make sure you set type correctly there is a useful summary on effective use here.

These shouldn't replace your normal meta tags, but exist in addition to them.
