.htaccess?

I've seen this done on some sites where if an image is linked from another Domain that it is either broken, denied or an error image shows up.

ex: http://www.mysite.com has an image called http://www.mysite.com/images/file.jpg

site: http://www.dumbsite.com uses my image directly from my site without saving it themselves so they are calling it with the full path. (<img src="http://www.mysite.com/images/file.jpg">)

How would i change my server to deny this and instead give an "error image?"

is this with .htaccess? or something else?

Then here -> http://httpd.apache.org/docs/mod/core.html#filesmatch

Instead of using a Location block in my example, you should use FilesMatch.

this should do the trick :

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: http://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.
