Do you use all the facebook og properties?

I just got some errors on
Required Property Missing og:title is required
Required Property Missing og:type is required
Required Property Missing og:image is required
Required Property Missing og:url is required

how can I define the og:image ?

 

I use FB og property on my blog.
I put those og on header.
Here's mine:

<meta property="og:title" content="Culinary Topics" />
<meta property="og:type" content="food" />
<meta property="og:url" content="http://www.culinarytopics.com/" />
<meta property="og:image" content="http://www.culinarytopics.com/images/banner/culinarytopics.png" />
<meta property="og:site_name" content="Culinary Topics" />

HTML:

 

are you using that on wordpress?

 

My blog powered by wordpress.
Please see my profile for the link to my blog.

 

OK, but that way it will send always the same url+image+description to facebook, from every single page

 

Yes, you are correct.
Still figure out how to make different url+image+description on every single page. But at this moment, all the same.
