 Some modules are available that extend Metatag with additional functionality:
 
+* Imagecache Token
+  https://www.drupal.org/project/imagecache_token
+  Provides additional tokens for image fields that can be used in e.g. the
+  og:image meta tag; ultimately makes it possible to actually use image meta

+* Transliteration
+  https://drupal.org/project/transliteration
+  Tidies up filenames for uploaded files, e.g. it can remove commas from
+  filenames that could otherwise break certain meta tags.

 * Domain Meta Tags
-  http://drupal.org/project/domain_meta
+  https://drupal.org/project/domain_meta
   Integrates with the Domain Access module, so each site of a multi-domain
   install can separately control their meta tags.
 
 * Select or Other
