Step 2) (Alternate)
Use this as an alternate Step 2 in order for any usergroup to the thumbnail images, regardless of whether or they have permission to access the thread or forum.

In attachment.php, find:

PHP Code:

    if (!($forumperms & $vbulletin->bf_ugp_forumpermissions['canview']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewthreads']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['cangetattachment'])  OR (!($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewothers']) AND ($attachmentinfo['postuserid'] != $vbulletin->userinfo['userid'] OR $vbulletin->userinfo['userid'] == 0)))
    {
        print_no_permission();
    } 


Change it to:

PHP Code:

// Change up the conditional below to allow everyone (including guests)
// to view thumbnails
// by Gio~Logist

if($imagetype == 'thumbnail'){


    // Allow anyone to view thumbnails

} else {

    if (!($forumperms & $vbulletin->bf_ugp_forumpermissions['canview']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewthreads']) OR !($forumperms & $vbulletin->bf_ugp_forumpermissions['cangetattachment'])  OR (!($forumperms & $vbulletin->bf_ugp_forumpermissions['canviewothers']) AND ($attachmentinfo['postuserid'] != $vbulletin->userinfo['userid'] OR $vbulletin->userinfo['userid'] == 0)))
    {
        print_no_permission();
    }

}
// end permission thumbnail change
