I want guests to be able to see the images and attachments... that's what we're selling. What I don't want is people using my bandwidth to post signature pics on other boards.

You may want to fix the spelling of your site name in the substitute image...

Ya, as you can tell I whipped one up in like 20 seconds:) Need to find a better substitute anyway.

This hack works great. Thanks.

Seems like any referer-based functionality is being broken as each day passes. My IE6 users have no referer so they get blocked too. Various firewall packages also hide the referer. :(

Seems like we're going to have to use sessions/cookies to get this to work right... ugh.

A slight variation for those who are interested:

I have a forum set up so guests wouldn't be able to see the attachments, and attachments themselves are shown right in the thread (not with a link).

So the following change in code does the following:
- all guest see an specified image instead of an attachment.
- whoever tries to link to your attachment image from the different site will not be able to show it. the replacement image is going to show up instead of whatever is in attachment for all unregged people.

Find this in attachment.php:
PHP Code:
$permissions=getpermissions($getforuminfo[forumid]);
if (!$permissions[canview] or !$permissions[cangetattachment]) {
  show_nopermission();
} 
and replace show_nopermissions(); with this:

PHP Code:
  header("Location: http://www.4adrive.com/img/attachment.jpg");
  exit; 
So here's how it should end up looking:
PHP Code:
$permissions=getpermissions($getforuminfo[forumid]);
if (!$permissions[canview] or !$permissions[cangetattachment]) {
  header("Location: http://www.4adrive.com/img/attachment.jpg");
  exit;
} 
Of course replace the url of the image to whatever you want displayed there.

I use the following image:

Thanks for the tip DR2000 -- I'll make those changes myself now. :)

And maybe you should note that the
Admin -> User Groups -> Modify -> Unregistered -> Can download attachments

should be set to 'No'.

BTW, 'member' is misspelled in your graphic. :p

Yish! Thanks for telling me. I was using that image for ages, and never knew. :)
