I have installed the Metatag module, along with ImageCache Token, but it just does not work.
I have tried many of the different available tokens in the Open Graph image field for my node, and none of them generate a og:image tag. For instance, I have tried:
[node:my_image]
[node:my_image:large:path]
[node:my_image:large]
[node:my_image:thumbnail]
if I hard-code a URL rather than use a token then it works, but that rather defeats the purpose. My logs contain no errors, and I remember to clear the cache each time. This is driving me nuts. Anyone know what might be wrong?
og:image was not defined, could not be downloaded or was not big enough. Please define a chosen image using the og:image metatag, and use an image that's at least 200x200px and is accessible from Facebook.
I have a hunch that that this has to do with the security vulnerability addressed in Drupal 7.20 and 7.21 where all image styles add a token to the url, to prevent DoS attacks, but not sure.
