Hey Bob, I just tested sharing an item on a FB page. The og:title, og:description and og:URL all worked, but the og:image did not show up in the share. I checked the source code and see the og:image tag filled in with the image URL, and checked that the image is valid. I realize you aren't FB support, but any ideas as to why the item image will not show up when shared on FB? Without the image the share isn't going to be very effective.
