You only have to enable plugin and it will work.
Simple Facebook meta tags legend:
og:title = article title
og:url = current url
og:type = article
og:description = First 250 characters from introtext*
og:image = First image from introtext or fulltext**
* You can manually set description characters limit in plugin.
** If image not exists in introtext, than plugin takes first image from fulltext
Any questions on: email@example.com
/* UPDATE VERSION 1.1 */
- added support for Joomla 3.x version
- fixed bug, if in description is ' or ", text has been cut off
Unfortunately it doesn't support Joomla 3 intro image and full article image settings.
I needed to have the my site use the intro image which is formatted best for Facebook. Luckily, because of the simplicity of the plugin and it's clean code, I was able to add a few lines of code to make do what I needed.
Thank you for your positive reply.
At this moment plugin looks into introtext if image exists, if there is no image plugin takes it from fulltext.
You can send me more details about "full article image" on firstname.lastname@example.org or email@example.com. If it will be possible I will make update of plugin.
