Not sure if you'd class this as a bug or feature request, but here goes.
The Open Graph image attribute:
If no default is given, it goes off to the WordPress preview page, which for always returns a black image with the WP logo. The site just spins forever.
If I set a default image, that works fine, this image will be shown on facebook.
However, to get any other post specific image onto facebook, I have to manually cut'n'paste an image url into the post specific SEO settings. Otherwise every single post I send to FB has the same default image. :(
For me this is a step backwards, I actually preferred it when FB just grabbed the first image and thumbnailed it. Essentially behaviour that worked for me, now requires extra, laborious manual work. :(
Can we have a setting to use first attached image to post/page, then fallback to default image, then fallback to WP preview service.
Or if not first attached image, first image URL found in body of post.
Or in the per page SEO setting, show a thumbnail chooser for all attached images, default to first, but let me click next/prev to choose right one (a bit like how you choose an image on FB when manually posting a URL on there).
