Put the media uploader in a metabox

I find it very unnecessary to have an “add image” button that brings me to yet another screen that will let me upload content to my post.

Ideally I would like to have a meta box with the option to add images directly in a meta box.

I managed to get some functionality by copy the source for the media-upload form and paste it in a meta box. The image I choose gets uploaded, however I doesn’t show any progressbar, and I need to find a way to list attached images below for better overview.

Anyone managed to do this?

Code:

function add_image_test() { 
?>
<script type="text/javascript">
//<![CDATA[
addLoadEvent = function(func){if(typeof jQuery!="undefined")jQuery(document).ready(func);else if(typeof wpOnload!='function'){wpOnload=func;}else{var oldonload=wpOnload;wpOnload=function(){oldonload();func();}}};
var userSettings = {'url':'/','uid':'2','time':'1300489693'};
var ajaxurl = 'http://xxx.com/wp-admin/admin-ajax.php', pagenow = 'media-upload-popup', adminpage = 'media-upload-popup',
isRtl = 0;
//]]>
</script>
