Unless otherwise indicated, the code snippets you see below should be placed into your theme’s functions.php file.

Here is the code to incorporate post format images on your website:

<?php
// Do NOT include the opening php tag shown above. Copy the code shown below.
 
// Add support for post format images.
add_theme_support( 'genesis-post-format-images' );

This code will search for images that are stored in the directory images/post-formats/ within your child theme.
