Letting member add their own photo to a site

[Cindy007]

Total newbie here so go easy please. I'm trying to make a site(using mysql and php) that will allow members to add a photo of themselves to their profile. I've seen some pretty complex photo gallery scripts out there but they are way beyond my understanding. I only want the members to add one or two photos , limiting the size of the pic and type(jpeg or gif). Is there a simple script or tutorial out there that can show me from start to finsih how I can do this. Thanks to anyone that can help.

$root = $_SERVER['DOCUMENT_ROOT'];
$tmp_file = $_FILES['ad_file']['tmp_name'];
$file_name = $_FILES['ad_file']['name'];
$file_size = $_FILES['ad_file']['size'];
$file_type = $_FILES['ad_file']['type'];
$ok_type = array('image/pjpeg','image/jpeg','image/gif');
$date = gmdate('m.d.y',time()-18000);
$time = gmdate('H.i.s',time()-18000);
	if (in_array($file_type,$ok_type)) {
		switch ($file_type) {
			case 'image/pjpeg':
			case 'image/jpeg':
				$ext = 'jpg';
				break;
			case 'image/gif':
				$ext = 'gif';
				break;
		}
	$file_name = "$date($time).$ext";
	move_uploaded_file($tmp_file,$root.'/path/to/members/photo/directory/'.$file_name);
	echo "Upload Complete<br />File Name = $file_name<br />File Size = $file_size<br />File Type = $file_type";
	} else {
	  // do error checking here
	  }
