Kill Attachments in Signatures

[Sean335]

Replaces signature images using your board's attachements with a message telling them to stop.

open includes/functions_showthread.php
find: (on lines 517 and 518)
$post['signature'] = parse_bbcode($post['signature'], 'nonforum', $vboptions['allowsmilies']);
$sigcache["$post[userid]"] = $post['signature'];
and add above it:
$post['signature'] = preg_replace("/\(.*?)\/attachment.php(.*?)\[\/img\]/i", "[i]attached pictures not allowed in signatures.", $post['signature']);

Using this method will block any img tag that uses attachment.php, if you want to block just ones that use your site, use something like:
$post['signature'] = preg_replace("/\(.*?)www.3.8mustang.com\/forum\/attachment.php(.*?)\[\/img\]/i", "[i]attached pictures not allowed in signatures.", $post['signature']);

There is also the option of just not allowing dynamic images.

There is also the option of just not allowing dynamic images.
some hacks require this to be turnt on though, such as the signature upload hack. This hack is a nice idea so lets keep on topic :rolleyes:

Whats so bad if an user would take an attachment in the sig?

Whats so bad if an user would take an attachment in the sig?bandwidth, database load, messes with the counters. My site just isn't a sig host, and too many people started using attachments, so I wrote that line.

you could try something like $post['signature'] = preg_replace("/\<img src=\"(.*?)\"\>/i", "<img onload=\"if(this.width > 500 || this.height > 200) {this.src='http://www.mysite.com/badimage.gif';}\" src=\"$1\">", $post['signature']); after line 518 of functions_showthread.php

(line 518 should be $post['signature'] = parse_bbcode($post['signature'], 'nonforum', $vboptions['allowsmilies']);). This will only work on javascript enabled browsers, though.

we do not allow images at all in signaturesthat option is built into your admincp as 'Allow [IMG] Code in Signatures' under User Profile Options.
