How Affect What Data Facebook Pulls for Sharing?

Hi,

How can i set an og:image, description and etc for when someone shares a page from my site?

For posts, it seems to pull the image I set as featured image, however, for pages it picks up the first image in row and the title of the page… sometimes images are missing, sometimes whole description?

I thought that whatever we eneter as Meta Title & Description is set for that too?

Please advise, thanks.
