Where does it call the link?!?!?

The images on my homepage are currently called by this line of code:

<li class=”post-<?php the_ID(); ?> thumb-big”><?php get_the_image( array( ‘custom_key’ => array( ‘thumbnail’ ), ‘default_size’ =>

Right now, each image on the homepage (https://www.rleighphotography.com) links to its specific post (the thumbs are pulled via making it the “featured image”). I’d rather the home images not have a link at all or link to the “galleries” page. There has GOT to be a way to remove the link, but where in the heck is it in that snippet of code? I can’t seem to figure it out.
