thanks...

you should use open graph tags (see "use proper open graph tags , large images generate great previews" , "using self-hosted objects") in header of webpages facebook determine metadata needs shared.

since using wordpress, either edit template file in theme defines page headers (normally header.php) or use facebook's official plugin.
