Portfolio image URL as meta tag
I'm using the Meta module in drupal together with the Token module.
In the meta module, I can define, by means of Tokens, what the meta tags for a node should be. All of this works fine except for the image field from the Portfolio nodes.
I have this token available:
but this token doesn't print the URL to the image (actually, I even don't know what this field would output).
Is there a way to have a token for the path/URL to the Image? (as the default Image field type does provide)?
