Failing to pull and display OG image

One final thing, that I've never seen before, is that Facebook is complaining that your SSL certificate is invalid:
developers.facebook.com/tools/debug/shar...punkpipeworks.com%2F

There are 4 Warnings, one of which is:

SSL Error
Can't validate SSL Certificate. Either it is self-signed (which will cause browser warnings) or it is invalid.

It does seem like your certificate is valid when I look at it in my browser, but it's something you may want to investigate further. If Facebook can't scan your page (which it looks like it's not since some of the other tags we are setting aren't being displayed) then even if you fix the og:image tag, Facebook still may not see it.

I don't know where to look to fix that issue. You may need to submit a bug with Facebook (developers.facebook.com/bugs), contact your host or contact your SSL provider for more information.

I hope that helps,
Alex
