Prohibit direct linking to your site

Sick of people direct linking images from your site ?

Put in .htaccess

This one would display the image owner.jpg :

RewriteEngine On
RewriteCond %{HTTP_REFERER} ^.*myspace.com.*$ [NC]
RewriteRule .*\.(gif|jpg|jpeg|swf|png)$ http://www.site.be/images/owner.jpg [NC]

This one would block direct linking, at all :

RewriteEngine On
RewriteCond %{HTTP_REFERER} ^.*myspace.com.*$ [NC]
ReWriteRule .*\.(gif|png|jpg|jpeg|swf)$ - [F]
