Publicize Facebook – no thumbnails (G ok)

Hi,

i use the publicize Function and so far so good, it works.

But one thing: when i insert a picture in the post, at facebook there appears no picture – you can only see the Excerpt. Only when i set the picture as featured image you can see it on FB. Google+ works all variants fine (with featured and inserted pictures).

Have you a solution for me?
Thx.
