Are these facebook metatags correct?

Hi,

When I copy and paste a link (a blog post) from my site onto facebook, rather than displaying an image from the specific post and the title to the post it shows no image and just the general description of my website.

I am guessing that I am missing the correct metatags so facebook can pull the corresponding title and images to the post. I have tried to use the linter but I don’t understand it!

Please could someone tell me what I am missing.

This is what I have:

<meta property="fb:admins" content="123766564369201" />

<meta property="og:title" content="Worldette"/>
    <meta property="og:type" content="website"/>
<meta property="og:image" content="http://www.worldette.com/wp-content/uploads/2011/05/WorldetteW5-300.jpg"/>
<meta property="og:url" content="www.worldette.com"/>

Thanks so much!
