How to tell if an image is being hotlinked...

Is there anyway to be able to tell if an image you are hosting is being viewed on another site, and if so tell which image it is and run a script when it is viewed?

thanks

 

well, you can see my blog for an example of image hotlinking.

you can stop it with .htaccess mod_rewrite

 

I had a look but couldnt find the article. can you give me a direct link?

i am not trying to stop people hotlinking, i just want to run a php script that will update a database everytime an image is viewed on any site.

 

Couple of ways you could do it, are you wanting to track all images or all images from a particular location, gimme a look at an example url of an image you want to track.

I would rewrite image urls to a php script, lets assume your images are in /hotlinked/

RewriteEngine On
RewriteRule ^/hotlinked/(.*)$ count_my_images.php?image=$1

Code (markup):

count_my_images.php =

<?
if( file_exists( sprintf( '/hotlinked/%s', $_GET['image'] ) ) )
{
  update_my_data_base( $_GET['image'] );
  echo file_get_contents( sprintf( '/hotlinked/%s', $_GET['image'] ) );
}
else
{
 echo file_get_contents( '/hotlinked/404.image.jpg' );
}

PHP:

That code prolly won't actually work for you, is an example, gimme some more details and I'll write something that does.....

 

okay, thanks. i will mess around with the code you gave me.
