When I send a link through something like Facebook there is a blank white thumbnail. How can I make sure there is an appropriate picture next to my link when I share it?

I thought perhaps the first picture on my wiki would appear in the thumbnail but that is not so.

I'm brand new so apologies if this is old ground for you guys :)
