Blogger vs WordPress Blog

When I publish a new post, it is auto posted to my website's Facebook page. But the image is not correct. The post is showing either my logo, or the page header. It's not using the image included in the post, or the image on the recipe (food blog). If I post manually I can use whatever photo I wish but I'd like see if I have a wrong setting on the auto post.

The blog I need help with is www.sugaredkitchen.com.
