Facebook og:image not working

I've dropped the following code into the head.php file so that when someone pastes my website URL into facebook as a link, it will pull up the details/image I want displayed on the facebook link:

<meta property="og:title" content="Island Cafe Racer: Hand Built Cafe Racer Style Motorcycles on San Juan Island, WA."/>
<meta property="og:description" content="es and construction videos on building your own cafe racer."/>
<meta property="og:image" content="http://www.islandcaferacer.com/facebook_islandcaferacer.jpg"/>
<meta property="og:url" content="http://www.islandcaferacer.com"/>
<meta property="og:type" content="website"/>

unfortunately this doesn't seem to work. When I use the FB linter, http://developers.facebook.com/tools/debug, it doesn't see any of the above code.

Is there a better place for the code so that FB scrapes it correctly?

Thanks,
