preventing direct URL's

[Anon]

hello,
i have a web site which will be a free clipart site. itinvolves a small search engine as well as thay are organized by categories.

i have no problem with people saving the images...it is actually encouraged. what i do want to prevent is people putting links to my clipart on their site...thus wasting my bandwidth. is this possible?

You can accomplish this using apache!! Just put this code in your <b>httpd.conf</b> file.

SetEnvIfNoCase Referer "^{http://www.yoursite.coml/"} local_ref=1
<Directory /usr/local/apache/htdocs/images/>
order deny,allow
deny from all
allow from env=local_ref
</Directory>

...have fun...

Max's method will work if you have Apache. If not, you could build an include file and put it at the top of all of your pages except your "entry" page. Have the include check the $HTTP_REFERER variable. If the referer is not on your site return an error. I haven't done this, but it should work.
