Pregunta Subir imagen y datos sin recargar pagina

Haber, os cuento:

Tengo un problema a la hora de trabajar con el envios de imagenes y datos mediante ajax. Quiero conseguir en un formulario enviar una imagen sin que se recarge la pagina (Esto lo consigo), y una vez subida la imagen rellenar los datos del formulario. Uno de esos datos es el nombre de la imagen. Tengo que pasar el nombre de la imagen a un input del formulario pero no soy capaz. Os pongo el codigo:

jmusic.html.php (Formulario):

<script type="text/javascript" src="http://localhost/components/com_jmusic/inc/ajaxupload.js"></script>

//Este esl formulario par asubir la imagen
<fieldset ><legend>Ajax Image Upload</legend>
<form onSubmit="return disableForm(this);" action="wizecho_upload.php" method="post" name="f" id="wizecho" enctype="multipart/form-data">
<input type="file" name="file" id="archivo" />
<button onClick="return disableForm(this),ajaxUpload(this.form,'<?php echo $mosConfig_live_site;?>/components/com_jmusic/wizecho_upload.php', '&lt;br&gt;Uploading image please wait.....&lt;br&gt;');return false;">Upload Image</button>
</form>
<div id="UPLOAD"></div>
</fieldset>

....
....
//Formulario de datos
<form action="index2.php" method="post" name="adminForm" id="adminForm">
.....
.....
//En este imput quiero añadir el nombre de la imagen una vez procesada
<input class="inputbox" type="text" name="imgfilename" id="imgfilename" size="40" readonly="true" value="" />
.....

ajaxupload.js (Este scipt es el que hace posible subir la imagen sin recargar la pagina):

<!--
alert("Ha cargado el script");

var myDomain = "";

if ( document.domain!="localhost" ) {
myDomain = /(http?:\/\/[^\/]+)/.exec(window.location.href)[1] + '/';
} else {
myDomain = "http://localhost/";
}

function disableForm(theform) {
if (document.all || document.getElementById) {
for (i = 0; i < theform.length; i++) {
var tempobj = theform.elements[i];
if (tempobj.type.toLowerCase() == "submit")
tempobj.disabled = true;
}

return true;
}
}

wizecho_upload.php (Este ultimo, gestiona la imagen, la sube, cambia el nombre, ect):

Como podria hacer para que una vez subida la imagen recuperar el nombre de esta y añadirlo al input:

<input class="inputbox" type="text" name="imgfilename" id="imgfilename" size="40" readonly="true" value="" />

Os agradeceria muchisimo alguan ayuda, he probado muchos metodos pero no consido naga. Saludos y gracias!!!
