Attachment and avatar hotlinking protection (1.0.1) · **Released**: 01-02-2003

Support in this thread or by email (preferrably thread)

vBulletin 2.2.x (tested on 2.2.9)

Prevents people from linking to attachments and custom avatars on your forum from other sites.

Example:
Attachment hotlinking protection: Click and watch the redirection message. You are then taken straight to the post containing the attachment.

Custom avatar hotlinking protection: Click and watch the redirection message again. This time you are taken to the user's profile.

When the attachment is linked to via an img tag, it is shown as a red x in IE, or a torn paper in Mozilla.

Modifications:
2 file modifications
/forum/attachment.php
/forum/avatar.php
1 new template
redirect_wrongreferrer

Updates since 1.0:
Added custom avatar hotlinking protection

Modifications since last version:
2 file modifications
/forum/attachment.php
/forum/avatar.php
1 template modification
redirect_wrongreferrer

For upgrade instructions see the text file.

Note for people who have problems getting the avatar hotlinking protection to work: Try this code in the avatar.php modification instead of mine

excuse my ignorance, but how does one link an attachment or avatar via the [ img ] tag?

DrkFusion · #23 01-03-2003, 05:21 PM

Let me try and show you

Right click on an attachment or avatar at your site. Go to Properties

You will see a URL in the Address (IE) or Location (Mozilla) box. Select it and hit Ctrl+C.

Then place the URL inside [ IMG][/IMG] tags.

http://forum.noxmedia.net/link.html
Right click on the properties and check the url

Smoothie · #26 01-03-2003, 05:30 PM

If I use that url in the [img tag] it does not display the avatar. here's the url i get:
https://vborg.vbsupport.ru/attachmen...&postid=338025

Hmm, weird, guess vBulletin.org doesn't like them

NTLDR · #28 01-03-2003, 05:48 PM

I expect vB.org has it set to know to allow dynamic images, ie images with ? in the URL.

Try this: Move this line

Code:

set_magic_quotes_runtime(0);

to just above

Code:

$c_url = parse_url($GLOBALS[HTTP_REFERER]);

nope

I'm running php4.3.0 locally and php4.2.3 at live forums.

nuno · #30 01-03-2003, 06:10 PM

hmm
seems to be working now
fix is attached

Odd, the one you posted doesn't work on my localhost.

Well, I'll put a link directly to your post in the original post for people who have the same problem as you did. Hopefully either solution will work
