First, create a new global phrase titled "threadtools_threadImg" with the text "Thread Images".

Next, create a plugin hooked at "showthread_complete" with the code:

PHP Code:

$vbulletin->templatecache['SHOWTHREAD'] = preg_replace('/<ul class="popupbody popuphover">/', '<ul class="popupbody popuphover"><li><a href="misc.php?do=threadImg&thread=
' . $threadid . '">\' . vB_Template_Runtime::parsePhrase(\'threadtools_threadImg\') . \'</a></li>', $vbulletin->templatecache['SHOWTHREAD'], 1); 


This will add the new menu item to the top of the list.
