Post on Facebook without article's image

Good morning I have a problem with the preview of images in a post on Facebook.
By publishing on Facebook the link to the article inserted on the site, the image of the article does not appear but rather the image of the logo. What can I do?
Thanks a lot.

Hello,

Try adding the intro and full image when you are editing the article. There's a tab "Images & Links" for each article. If this doesn't help, try installing an extension for open graph, such as www.phoca.cz/phoca-open-graph-plugin

I'll try, thank you very much.
