trouble with Facebook

Hey there.
Using Publicize, I just can’t get Facebook to take the image we’ve posted on our blog. It just default back to the website title image no matter what I try, and that includes trying all suggestions in this forum.

The Facebook debug page is telling me that I haven’t defined og:image, it can’t be downloaded or its the wrong size, yet further down the very same page it correctly lists and shows the image as a thumbnail.

Here’s the debug output : https://developers.facebook.com/tools/debug/og/object?q=http%3A%2F%2Fdrllz.com%2F%3Fp%3D863

What gives? How can I get this to work properly?
