Pinterest image is blank despite og:image tag on page

Question

On this page > http://matchcoverguy.com/kimballs-ice-cream-1920s-tall-universal/

When I click the "Pin It" button, the popup that appears has a blank image. Although, I have an open graph metatag there:

<meta property="og:image" content="http://matchcoverguy.com/wp-content/uploads/Kimballs.jpg"/>

Is there something else I can do to get the Pin-it button to pull the image?

Answer 1

Your image violates the 3:1 maximum image ratio;

It's also missing other tags, see http://developers.facebook.com/tools/debug for more information (though that tool doesn't currently mention the 3:1 max image ratio, it's mentioned in the docs)
