Whoever has the license of the pictures you are distributing with your template is targeting your customers. After the initial setup of my site with your template; I never knowingly wanted to use the images you included with it nor would they have benefitted me in any way. To find a copyright violation your licensed owner would have needed to crawl specific URL links that are not, nor have ever been in service of the site I made with your template.
They would have used your template to search for victims. An incredible disservice to anyone who has purchased a template from you.
