OpenGraph for Blogger
<!-- Begin Open Graph metadata -->
<b:if cond='data:blog.pageType == &quot;item&quot;'>
<meta content='article' property='og:type'/>
<meta expr:content='data:blog.title' property='og:site_name'/>
<meta expr:content='data:blog.pageName' property='og:title'/>
<b:if cond='data:blog.postImageThumbnailUrl'>
<meta expr:content='data:blog.postImageThumbnailUrl' property='og:image'/>
</b:if>
<b:else/>
<meta expr:content='data:blog.title' property='og:title'/>
<meta content='website' property='og:type'/>
</b:if>
<meta expr:content='&quot;en_US&quot;' property='og:locale'/>
<meta expr:content='data:blog.canonicalUrl' property='og:url'/>
<!-- End Open Graph metadata -->

Adding Open Graph metadata to Blogger is easy. Simply copy the code below and paste it into your template after the <header> tag.

A couple notes:

  • og:locale Should probably actually reflect the blog's locale instead of just being a hardcoded string. Unfortunately, Blogger only gives us en-us with a hyphen, instead of an underscore, so that won't work.
  • If you're using your blog as a personal profile, you may consider changing the second og:type from website to profile and adding your personal information
  • og:image Is only supplied if Blogger finds an image in the current post. However, not supplying og:image is invalid. You could provide an alternate image of your blog logo, or a Gravatar.
  • If you do something cool with this, I'd love to hear about it. pathawks@shortmail.com

Thanks for this
I have followed the steps above.

I have few images in my blog post uploaded from local.
I have added the code under the header tag in the template html.

Now when i am trying to share the post. i am getting preview of only image i.e. the first one.
Is it possible to get preview of all images ?

best Regards,
Saurav
