Installing and enabling the Open Graph - Content plugin that comes with JFBConnect is the first step. That plugin will try to automatically set the image for all of your content based on a few factors. You can then create 'objects' for a specific category of your site and have the image set specific to that article (as the category image or a specific image you define for the whole category).
Throughout your site, you can also use our Open Graph easy tags to define any tags specific to that page, like:
{SCOpenGraph image=http://site.com/image.jpg}
There's a lot of flexibility in our Open Graph implementation, but by just enabling the plugin for your component, that should setup some pretty good default values per-page.. and from there you can tweak things.
I hope that helps,
Alex
