[Mr-Moo]

If I go from the source provided in that link, I feel that the only modification that needs to be made is the following:

if($_POST['do']=="doupload"){
$vbulletin->input->clean_gpc("f","upload",TYPE_FILE);
require_once('./includes/class_upload.php');
$upload =& new vB_Upload_Attachment($vbulletin);
$upload->path = "./directory/of/choice/";
if (!($upload->process_upload($vbulletin->GPC['upload']))){
        eval(standard_error(fetch_error('there_were_errors_encountered_with_your_upload_x', $upload->fetch_error())));
    }
}

The items in red are what was modified/added.

Please let me know if this works.
