featured image for fb

Hello there,

I am using your plugin especially for fb, as my theme was pulling an image from the footer when sharing.
μ
I would simply like the image to be the post featured image, but it doesn’t work by default, so I suppose I made some mistake in the settings ?
(It does work if I am using your open graph field tool though, but I was looking for some way to make it “automatic”, feautred image, and that’s it.)
thanks if you can help…
