is it possible that shashin adds og:image meta tags for every image it inserts? Mayby it's also possible to insert a meta tag for every gallery image inserted? I just ask because the seo plugin doesn't "see" the images and therefore doesn't insert any tag or just insert the tag for the default image (e.g. blog logo). But if I insert a gallery (or just a single image) from picasa I'd like to the those images in the open graph tags.
