Hi !
Is it possible (and how) to rewite all request for pictures that do no
originate from my site to pass through a filter.

example
www.mysite.com/pic/pic23.jpg should be
www.mysite.com/referrer.php?pic=pic23.jpg

In pic.php I check if they have visited my site ( I set a cookie) and if
not .. watermark the picture.

I found something on the web that works a little but it doesn't rewrite
specifically enough .. any ideas ?

RewriteEngine On
RewriteCond %{HTTP_REFERER} !^http://(www\.)?yoursite\.com [NC]
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} ^http://.*$
RewriteRule \.(jpe?g|gif|bmp|png)$ /media/nohotlinks.png [L]
