The Best Way to Block Image Hotlinking
“Image Hotlinking” is when another website embeds an image from your site (usually without permission). This increases your bandwidth bill, is a potential security concern, and is generally a pretty rude thing to do. To prevent this in Drupal, add the code below to your sites/all/files/.htaccess file: # image hotlink protection <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{HTTP_REFERER} !^$ RewriteCond %{REQUEST_FILENAME} -f RewriteCond %{REQUEST_FILENAME} \.(gif|jpe?g?|png)$ [NC] RewriteCond %{HTTP_REFERER} !^https?://([^.]+\.)?domain\. [NC] RewriteRule \.(gif|jpe?g?|png)$ - [F,NC,L] </ifModule>
