Images - Updated June 2014 - Minimum size to place on your blog posts: 600 x 315.
Post Titles - are not sent to Facebook.
Author - is not posted either, but it is required by some sites, so IC requires it for everything to cover all scenarios.
Status Text - is the actual "post" to Facebook, and then our code will attach the file as well.
Promo URL - is sent over to Facebook
The post states, "posted by instantcustomer.com" because IC is posting the file on behalf of the user.
