Citizen's picture

Advertisement 6.x-2.2 module - I am having problems posting articles to Facebook. Instead of attaching the main image of the article to the post or no image, it's automatically attaching the tile ad images from the article page to the Facebook post. I'm wondering if anyone knows how to prevent this from happening. Recent changes in Facebook no longer gives the option to select "no image". We're also using the OpenPublish packaged distribution 6.x-1.16.
