I have html_meta_tags active, which is creating all the meta and og tags I need, however, I don't know how or why the og:image is using the size thumbnail that it is (90px or so).
Apologies if this is a simple question, but I can't seem to figure out how to set or change the dimensions in the admin, and after quite a bit of googling/searching the forums, I still haven't come up with a solution.
