$path = "../upload/picture/";
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST"){
	$name = $_FILES['file']['name'];
	$tmp = $_FILES['file']['tmp_name'];
	if(strlen($name)){
		list($txt, $ext) = explode(".", $name);
		$file_pic = time().substr(str_replace(" ", "_", $txt), 255).".".$ext;
		if(move_uploaded_file($tmp, $path.$file_pic)){
			$sql =	" INSERT INTO picture (pic)  VALUES ('$file_pic') ";
			$query = mysql_query($sql) or die("Can't Query");
			echo "	<script language='javascript'>
					window.location='picture.php?a=$file&&b=$file_pic';
					</script>
