Show featured image in post?

Hello,

I am using this plugin with custom fields. I have the below custom template. I would like to add a featured image for each post/staff-member. How can I reference the featured image from within the custom template?

Thank you,
Peter.

<div class=”staff-directory”>

[staff_loop]

<b>[name]</b> – [position] – [email] – [phone_number]
[bio_paragraph]

<div class=”staff-directory-divider”></div>

[/staff_loop]

</div>
