Kill Attachments in Signatures

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)

PHP Code:

$post['signature'] = parse_bbcode($post['signature'], 'nonforum', $vboptions['allowsmilies']);
$sigcache["$post[userid]"] = $post['signature']; 


and add above it:

PHP Code:

$post['signature'] = preg_replace("/\[img\](.*?)\/attachment.php(.*?)\[\/img\]/i", "[i]attached pictures not allowed in signatures.[/i]", $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:

PHP Code:

$post['signature'] = preg_replace("/\[img\](.*?)www.3.8mustang.com\/forum\/attachment.php(.*?)\[\/img\]/i", "[i]attached pictures not allowed in signatures.[/i]", $post['signature']);

you could try something like

PHP Code:

$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

PHP Code:

$post['signature'] = parse_bbcode($post['signature'], 'nonforum', $vboptions['allowsmilies']); 


). This will only work on javascript enabled browsers, though.

that option is built into your admincp as 'Allow [IMG] Code in Signatures' under User Profile Options.
