When posting a link to an article, Facebook fetches the logo instead of the main picture as the thumbnail for the article. How can that be fixed?
andrewwinkler Hi Facebook use Open graph tags to get correct thumbnail on the page you shared its using correct image http://prntscr.com/ub7mpg To get exact image you can use Open graph extension from Joomla extension directory and use them.
FB uses the intropicture as preview on the private wall but on the business page it uses the site's logo from the header. Which open graph extension do you recommend for that purpose?
andrewwinkler Hi If OG tags are not present it pick the thumbnail randomly. You can try the extension from here : https://extensions.joomla.org/tags/open-graph/ based on the features and reviews.
I was able to fix the problem using TAGZ Open Graph. Thanks a lot for your advice.
