If you can configure your own web server, which is usually not possible in low-budget hosting packages, there is this option via changes to .htaccess:
# Download / Load content only from explicitly allowed sites # Example: Allow everything from own domain, nothing from external sources: Header set Content-Security-Policy "default-src 'none'; frame-src 'self'; font-src 'self';img-src 'self' siwecos.de; object-src 'self'; script-src 'self'; style-src 'self';"
