I have installed the Metatags module along with the Open Graph and Twitter Card extension modules. In my default content type, I have added an Image field that allows an image to be uploaded for use on Facebook and Twitter.
Now I cannot get the Metatags module to accept this image custom field as the entry for the og:image and Twitter Card Image fields. I've tried entering [node:field_image] but the meta tags do not get added to the source code. If I enter a URL the tags appear.
How do I get Metatags to dynamically include a corresponding image for each page in the Open Graph and Twitter Cards metadata?
