Even though in Global config I have this checked:
1.4 Use post images in Facebook wall thumbnail
I also have an image specified here:
1.5 Default thumbnail image
But when I click "share", the only thumbnail options I'm given are those from my sidebar, which are completely unrelated to the post. The post has an image in it. Why can't I chose that one? Or at the very least choose the default thumbnail image I specified in the settings (1.5)?
