External images posts to facebook

WP Facebook Auto Publish is coded such that it will select the featured image first and if no featured-image is set then it will select the first image in the post content.
The external image url support and other settings for image preferences is only supported in the premium plugin.
Hope this helps.
Please let us know if you have any questions.
Thank you.
