Ogg Image

From the Facebook Debug Tool, it seems like Facebook can't access the image at all. The dimensions aren't necessarily wrong, Facebook just can't fetch the image at all. You can see that because in the og:image listing further down in the page, there is no image shown there. Usually it will show any images it finds, even if they are too small.

I tried running your site through a few different checker tools. Most passed, but one that has been consistently reliable for us in the pass always indicates your site is returning a 406 error code when loading any page (the image or even the page itself):

I'd have to recommend:
* Looking through your Apache access logs to determine what response code is being returned when Facebook scans your page
* In general, don't use images with spaces in the file name. Spaces are not recommended as the behavior is not always the same when loading in different browsers and tools

I hope that helps get you started,

It's likely a change on Facebook's end with the scraping of the page and fetching of the images. It could be a temporary bug on their part or it could be that they fixed another issue which broke spaces (or expects a different format).

That's why I said "in general" above, since spaces are somewhat indeterminate of how a browser or automated tool will handle them. Some use it as a space, some switch spaces to %20 and others do different things. Not using spaces may help prevent other issues with Facebook or other services (or browsers) in the future as well.

Glad to hear things are working now,
Alex
