Es müsste so ähnlich funktionieren:
...... PREVENTING PEOPLE FROM LINKING TO YOUR IMAGES......
If you want to prevent other websites from linking to your images then add the following to the '.htaccess' file:
# Rewrite Rule for images
RewriteCond %{HTTP_REFERER} <URL of page accessing your domain
RewriteRule ^(.*)$
http://<same as above URL>
You would replace the <URL of page accessing your domain> above with the domain name and path of the page that is referring to your domain. For example:
www.their-isp.net/users/mypage/
The RewriteCond directive states that if the {HTTP_REFERER} matches the URL that follows, then use the RewriteRule directive. The RewriteRule directive will redirect any reference back to the referring web page.
