No image data inserted?

I don’t get any of the following tags inserted for posts. It does, however, insert it for the main page. Or rather, they are empty on the other pages/posts.

<meta property=”og:locale” content=”en_us” />
<meta property=”og:type” content=”article” />
<meta property=”og:image:width” content=”” />
<meta property=”og:image:height” content=”” />
<meta property=”og:image” content=”” />

My site has the following structure for posts: /YYYY/MM/DD/this-is-the-title-of-the-post/

It seems to work if I specify a default image URL for all three configuration fields. But I’m somewhat confused as to why it wouldn’t tell me that this is required ??
