title: Facebook multiple og:image tags - Which is Default?
body: <p>My web site specifies multiple og:image tags, and I'd like to control which one is the default. Does it have something to do with the order in which they're specified?</p>
  
  <p>Right now the images are appearing in the link post selector in the order #3, #1, #2 (#3 being the default), which seems quite unusual.</p>
  
  <p>Thanks for any insights you might have.</p>
