ShareThis facebook posts previews are perfect, but posts empty images I have been having problems with facebook integration, and I know there are lots of other posts about this as I've been looking through lots of them. I see plenty of information about FB picking the wrong image, but in my case, the image is correct, and the preview of what is going to be posted from ShareThis is perfect. Even the facebook debugger tool has it all correct, but when I actually post it to facebook, the image is just empty. 

What confuses me even more is that 2 of my other content types work, and the third doesn't. All 3 are defined in the same fashion, using the metatags open graph module to define the tokens for the meta data. In each page, the source is the same, and the og:image tag is always correct. When copying the image URL out of the source and browsing, the image loads perfectly. 

I swear sometimes that facebook just does whatever it feels like sometimes. Anybody have any advice on why 2 of 3 content types work fine, but the 3rd never works?

I have looked at the settings for each imagefield, and they are all nearly identical. None of them are being stored in specific folders, they are all publicly accessible. As an example, the URL http://natureupnorth.org/encounter/mark-martin/smaller-haystack gives me no problems in the facebook debugger, previews fine, but results in just an outline of an image on facebook.

Any help greatly appreciated.

That og:image gives me a 403 error.  Is this set to require a logged in user?
