wrong image (og:image) displayed

If you want to set a default og:image for the whole site, the best place to do so is in the Open Graph -> Configuration area. In the 'Defaults' box, add:That will set it on each page of the site. You can still override it by enabling the Open Graph plugins or using the {SCOpenGraph ..} Easy Tag.

As for why Facebook may not be picking it up, they cache the tags from each page. It can take them anywhere from 1-7 days to 'see' the updates. You can run your page through their debug tool, below, to check the update as well as update their cache for the page you test:
developers.facebook.com/tools/debug

I hope that helps,

Hehe.. glad to hear it.. I'll take the credit for.. uh.. whatever happened Facebook obviously uses a lot of caching. Sometimes waiting a day (instead of pounding your head against the wall) is the best course of action.

As always though, should you need anything else, just let me know.

Thanks,
Alex
