Sharing on facebook always has the flag as pic no matter what

I have deleted the flag in every location on the site but still the american flag shows up when I do a facebook share. Seems to be tied to the background image but even if removed it cones up. I need the billboard image on main index page to be the share photo for facebook as we go live today. can someone please help me asap PLEASE.
