Hey, I am writing in hope of getting a hint why this happens:
When I choose an item article to be shared on facebook, I get only the link displayed in my profile, without any picture. I am new to k2 and I am not sure what must I do in order to get the picture of the item displayed as well (I used another sharing system for the core Joomla content articles and it automatically fetched the first picture displayed on the article's body). 

I also assume that the meta - description is what appears as a descpription bellow the title on facebook's wall?

Besides that, many grats to JoomlaWorks for their fantastic component and many grats to all here in the community who help us noobies get things to work! :D
