I'm managing a video blog. The blog contains a main youtube video on the homepage and several thumbnail images of other videos elsewhere.

I have a share button for the main page and the single posts pages and have added opengraph to specify the used image.

For some reason facebook ignores my opengraph image and uses othe images it finds in the page...

the header looks like this: (for the homepage)

    <!-- Facebook Opengraph -->
    <meta property="fb:app_id" content="155967927783206" />
    <meta property="og:url" content="http://mttv.co.il/2010/12/%d7%9e%d7%a4%d7%92%d7%a9-%d7%a1%d7%99%d7%99%d7%a2%d7%95%d7%aa-%d7%92%d7%a0%d7%a0%d7%95%d7%aa-%d7%9c%d7%93%d7%95%d7%a8%d7%aa%d7%99%d7%94%d7%9d-1959-2010-%d7%91%d7%9e%d7%a2%d7%9c%d7%95%d7%aa/"/>
