If you have trouble posting your blog posts with images on Twitter and Facebook, it might be related to missing Open Graph tags in your websites meta data.
Open Graph tags were developed by Facebook to improve the correspondence between websites and social media platforms. They are the information in your meta tags which tells the respective social network which image to pull and display in an automatically generated link preview when sharing a URL. So if you would like to post a link with an automatically generated link preview, displaying the featured image, title and teaser comment of your blog post on Twitter, Facebook, Google+ etc., you should set Open Graph Meta Tags for your website.
You can either add the respective parameters to the HTML of your Website or blog or let Blog2Social do this job for you.
