Previously you answered a question about how to select the image used when a blog post is posted on Facebook by saying:
If you are posting as posts or as notes, use WordPress' built in "Featured Images" to identify which image WPBook should post.
That works, but it also adds an extra image to my WP post that I don't want. As a workaround, I can create the WP post, select the Featured Image and Publish. This gets the WP post on FB with the correct thumbnail. Then I go back to WP, remove the Featured Image, and update.
Is there a less cumbersome method to do this?
