Hi,

> $_SERVER[HTTP_REFERRER] does not help. 

Not sure if you've got it that way in your code, but that might be because
it's spelt "HTTP_REFERER" - yes, it's wrong, you're right, but you have to
live with it :-)

I think you may also need to quote it like this, but I'm not sure:

  $_SERVER['HTTP_REFERER']

Also, if you're on Apache, there are numerous ways to block this sort of
image hijacking using .htaccess files - a couple of minutes on Google will
doubtless turn up all sorts of ideas.

Cheers
Jon
