Why doesn't an image load for Facebook link post previews?


Facebook’s API scraper cannot load specific images at times, resulting in link post previews without photos. Facebook's debugger may show data, but the API scraper does not. Unfortunately, Gain cannot produce a proper link preview when the API scraper doesn't return data to us.
Even so, if a link post preview doesn't show up on Gain, it will most certainly show up on Facebook once the post is published. We understand this situation isn't ideal, so there are a few workarounds: 
  • Make sure Open Graph meta tags are correct if you have trouble seeing links post previews of content from websites you manage. 
  • Review Facebook's recommendations for using Open Graph meta tags on your website to maintain control over how your links will appear once published. With explicit OG tags in place, Gain can create proper link post previews. If you would like more information on using Open Graph meta tags on your website, you can visit this page.
  • Use the photo post format. Upload your preferred image to your post and paste any links in the post message field. 
  • Share directly on Facebook's UI. If you need to have an exact idea of how Facebook will display a link when published, you can share it on Facebook and see what comes up.
