This problem has been dealt with. Unfortunately, the solution has not yet been posted, and I could not reply to this topic. (not comunity)
I would be pleased if all images would be seen in Facebook.
What I have tested so far:
- the link in the database is right
- The API version was increased to 2.1
- The link in the Facebook page is also true, however, not shown.
Any other Channel works fine, but FB one takes random image every time. Why?
I clicked the link you've posted above, and got got some answer of FB Crawler: "Warnings That Should Be Fixed
The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags".
Well.. How I can fix this "og:image property"? What should I do to repost content to the FaceBook with its image if the image exists and repost content with no images at all if there're no images in the text?
In most cases, when Facebook picks a different image (than the post image), it is caused by loading issue (Facebook cannot load it from your side) or the image is small and it does not meet Facebook requirements.
To check it, you can inspect your site with Facebook debugging tool Facebook Sharing Debugger: developers.facebook.com/tools/debug/sharing/
Please, post the image sharing result (generated with the Sharing Debugger).
PD: If your posts don't have an image at all, you can define a default image (Options) or implement Facebook Open Graph tags (Joocial has a plugin to generate tags) to guide Facebook scrapper.
