Yes I do, it's all ok

I've an update for that trouble, looks like thats a trouble of the wysiwyg editor, when I insert inline a thumbnail with the wysiwyg disabled, it insert a [ATTACH ] tag but if I switch from textual editor to wysiwyg and than I switch again to text it change the attach tag to img tag!

Ok, now there is something of weird...

Test 1: I tried to install a clean vBulletin 4.2.2 on my official server, using a new DB, after I installed it I tried to verify the inline trouble and that clean vBulletin have that trouble.

Test 2: I've a fresh installed local Virtual Machine with FreeBSD, like the official server, with about all package installed, I tried to installa a fresh vBulletin 4.2.2 but that installation have inline image trouble too...

Test 3: Fresh install of lastes stable Debian with Apache 2 (not Nginx as official server), than I've installed a fresh vBulletin 4.2.2 and... It goes! There isn't inline trouble!

After a fast debug I found similar errors on test 1 and 2:

Warning: preg_match() [function.preg-match]: Compilation failed: invalid range in character class at offset 23 in ..../includes/class_wysiwygparser.php on line 481

Than I tried to understand it and editing includes/class_wysiwygparser.php at 481 I find:

		if (preg_match('#attachment.php\?attachmentid=(\d+)#si', $img_url, $matches) AND preg_match('#class=(\'|"|)([a-z0-9_-\s]+)?\s*previewthumb\s*([a-z0-9_-\s]+)?(\\1)#si', $fullurl))
		{
			return '[ATTACH=CONFIG]' . $matches[1] . '[/ATTACH]';
		}

To test it I got the 2 variables ($img_url and $fullurl) and I make a file test.php
<?php
$img_url ='http://192.168.1.55/attachment.php?attachmentid=36&amp;stc=1';
$fullurl ='<img src="http://192.168.1.55/attachment.php?attachmentid=36&amp;stc=1" attachmentid="36" alt="" id="vbattach_36" class="previewthumb">';

if (preg_match('#attachment.php\?attachmentid=(\d+)#s i', $img_url, $matches) AND preg_match('#class=(\'|"|)([a-z0-9_-\s]+)?\s*previewthumb\s*([a-z0-9_-\s]+)?(\\1)#si', $fullurl))
{
echo "it's ok";
}
?>

If I run that file on freebsd server it give error:
Warning: preg_match(): Compilation failed: invalid range in character class at offset 23 in x.php on line 5

But if I run it on the Debian server it goes!
That's really strange, some suggest to fix it?
