[SOLVED] renaming image before upload

[justAnoob]

I'm looking to rename the image before it is uploaded to the server. Can someone point me in the right direction. The user has a textbox on the page so they can type in the name of the image they are uploading. I want them to be able to give it a name insted of using the actual filename. Here is what we got so far for the upload.

<?php
$itemname = mysql_real_escape_string($_POST['itemname']);
$description = mysql_real_escape_string($_POST['description']);

define ("MAX_SIZE","1000");
function getExtension($str)
{
$i = strrpos($str,".");
if (!$i)
{
	return "";
}
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}

$errors=0;
if(isset($_POST['Submit']))
{
$image=$_FILES['image']['name'];
if ($image)
{
	$filename = stripslashes($_FILES['image']['name']);
	$extension = getExtension($filename);
	$extension = strtolower($extension);
	if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "gif") && ($extension != "png"))
	{
		echo '<h1>Unknown extension!</h1>';
		$errors=1;
	}
	else
	{
		$size=filesize($_FILES['image']['tmp_name']);
		if ($size > MAX_SIZE*1024)
		{
			echo '<h1>You have exceeded the size limit!</h1>';	$errors=1;
		}

		$image_name=time().'.'.$extension;
		$newname="userimages/".$image_name;
		$copied = copy($_FILES['image']['tmp_name'], $newname);
