Absolutely! The Open Graph tags are what you use to describe your pages to Facebook to be used in posts and other areas. To setup Open Graph tags, install the Open Graph - Content plugin that's in the main zip file you can download from this site. The Open Graph plugins are new with the v4.3 release. Publishing that plugin will automatically set the title, description and image for your page based on the content of the article and will use the first image it finds.
Beyond that, you can:
* Go to the Open Graph configuration section of JFBConnect and go to the Objects area. Create a new "Content - Article" object and select the main category you want to use. You can then setup a little more about how the Open Graph tags will be set (number of characters/words from article to use as the description, where to find the image for the articles in those categories, etc).
* For the most control, in the article itself, add any of the following tags:
{SCOpenGraph title=Best Title}
{SCOpenGraph description=Description for the page}
{SCOpenGraph image=http://www.site.com/best-image-for-article.jpg}
If those tags are in the article, they will be used for the Open Graph tags instead of any of the automated stuff above. More flexible, but more work per article. So, get the automatic stuff working, and then tweak any articles you really want to be tailored for Facebook posts!
Hope that helps, but if not, let us know,
