Can Floating Sharebar only Share Feature Image on Pinterest???

I was hoping to use the floating share bar and when a user clicks on the Pinterest button my goal was to allow them to pick any of the photos on the page to share on Pinterest.

I’ve looked through the settings numerous times and can’t see to find an answer. Am I missing something? Is there an easy way to set this up?

If you try the sharebar on the site below, this demonstrates how I was hoping WP Socializer might work.
