I have some problems with facebooks open graph and I have no idea what might cause them. I use 'All in One SEO Plugin' to create the open graph meta information, which it does correctly.
When you look at the source you see that the attached og:image is http://y2b-blog.de/wp-content/uploads/2014/01/Dancing-Dreams-Poster.jpg
which is a 564x800 px image. It is also referenced here as og:image https://graph.facebook.com/706205779446106
But when I try to post the link on fb, this image is not used. Plus, the facebook debugger tells me that the attached image is too small: http://y2b-blog.de/wp-content/uploads/2014/03/Bildschirmfoto-vom-2014-03-12-155940.png
For some reason facebook uses a wrong 40x40px version of the image and I can't figure out why and where it takes it from.
It would be really nice if somebody could have a look at this issue and tell me ideas how to solve it.
Thanks a lot!
