Can't find footer image that is broken

I have a footer image that is broken on a Multi-Site footer. It only appears on a single site that is using the Nova theme. I went to the footer.php file but it's not located there or in the ePanel settings. I have found the direct link (http://clblegalnurseconsulting.com/wp-content/themes/Nova-default/images/legalnursesymbol.png), but the folder containing this specific site in the cPanel only has a cgi folder and no WP folders. I am needing to remove this file but can't find it. Any help would be greatly appreciated.
