[Plugin: WP Facebook Open Graph protocol] Blog images do not show when sharing on Facebook

Hey,

I will try to be as specific as possible. Thanks for any replies.

Problem: when sharing links from our blog on Facebook, proper images wont show up for thumbnail.

Facebook loads many random images from our blog (most likely from sidebar). However, they wont load first image from the blog post.

What I did already:
* I have manually inserted a code og:image with specified image url for thumb; still, fb loaded many images but not this
* I have installed your plugin and put my user ID from open graph – not sure if it works properly or not; plugin is obviously activated; thumbs do not show up properly (fb only grabs images from sidebar).
* I tested my url with FB debugger. I get one critical error. Here are the results.

Me and my girlfriends are extremely frustrated with those issues. She prepares healthy dishes for her blog but sharing those withouth images is pointless.

We’d love to get any advice from you,
Regards,
Simon and Paulina.
