I wrote a function to resize and upload images...it works, but only for one image. So if I call the function three times, I end up with 3 copies of the last image.....

function uploadImage($name,$width,$height,$size,$path='content/user_avatars/')
{
    //===================================================
    //Handle image upload
    $upload_error=0;
    //Picture
    $img = $_FILES[$name]['name'];
    if($img)
    {
        $file = stripslashes($_FILES[$name]['name']);
        $ext = strtolower(getExt($file));

        if($ext!='jpg' && $ext!='jpeg' && $ext!='png' && $ext!='gif')
        {
            $error_msg = "Unknown extension";
            $upload_error = 1;
            return array($upload_error,$error_msg);
        }

        if(filesize($_FILES[$name]['tmp_name'])>$size*1024)
        {
            $error_msg = "Max file size of ".($size*1024)."kb exceeded";
            $upload_error = 2;
            return array($upload_error,$error_msg);
        }

        $newFile = time().'.'.$ext;

        resizeImg($_FILES[$name]['tmp_name'],$ext,$width,$height);
        $store = copy($_FILES[$name]['tmp_name'],$path.$newFile);
        if(!$store)
        {
            $error_msg = "Uploading failed";
            $upload_error = 3;
            return array($upload_error,$error_msg);
        }
        else
        {
            return array($upload_error,$newFile);
        }
    }
}

//=========================================================================================

//Helper Functions
function getExt($str)
{
    $i = strpos($str,".");
    if(!$i)
    {
        return "";
    }
    $l = strlen($str)-$i;
    $ext = substr($str,$i+1,$l);
    return $ext;
}

function resizeImg($file,$ext,$width,$height)
{
    list($aw,$ah) = getimagesize($file);
    $scaleX = $aw/$width;
    $scaleY = $ah/$height;

    if($scaleX>$scaleY)
    {
        $nw = round($aw*(1/$scaleX));
        $nh = round($ah*(1/$scaleX));
    }
    else
    {
        $nw = round($aw*(1/$scaleY));
        $nh = round($ah*(1/$scaleY));
    }


    $new_image = imagecreatetruecolor($nw,$nh);
    imagefill($new_image,0,0,imagecolorallocatealpha($new_image,255,255,255,127));
    if($ext=='jpg'||$ext=='jpeg')
    {
        $src_image = imagecreatefromjpeg($file);
    }
    else if($ext=='gif')
    {
        $src_image = imagecreatefromgif($file);
    }
    else if($ext=='png')
    {
        $src_image = imagecreatefrompng($file);
    }
    imagecopyresampled($new_image,$src_image,0,0,0,0,$nw,$nh,$aw,$ah);

    if($ext=='jpg'||$ext=='jpeg')
    {
        imagejpeg($new_image,$file,100);
    }
    else if($ext=='gif')
    {
        imagegif($new_image,$file);
    }
    else if($ext=='png')
    {
        imagepng($new_image,$file,9);
    }

    imagedestroy($src_image);
    imagedestroy($new_image);
}

I have a form with two upload fields, 'face_pic' and 'body_pic', and I want to upload these two to the server and resize them before storing. Any ideas?
