Hi,
It seems that the post images inserted in thumbnail media / detail media are not picked up by Facebook, LinkedIn, Google+ etc. social networks when the post is shared.
Maybe this has something to do with an error that I get from NFGB Open Graph plugin. On each post I get this error:
Open Graph+ Warning: Image id 3514 rejected(600×472) too small for ngfb-opengraph (1200×630 cropped).
Actually I rather would not use the NFGB plugin since I prefer WordPress SEO. Is there a way to get the blog post images show up when shared on social networks? I have never had this kind of problem with any other theme. Where should I insert the images?
