image upload pretty complex

[djwinder]

hi everyone

here is a copy of the code i am trying to execute which is intended to upload an image, detect the images file type, generate a thumbnail and place the path to both the image and the thumb in the database. Here is the code and below that the errors output by php. If anyone can shed any light on this i would really aprishiate it, i have tired a few things wiht no success.

<?php

echo "got to checkpoint 1";
include ('c:/web/db_connect.php');
echo "got to checkpoint 1";
$message1 = ""; 
$message2 = ""; 
$message3 = ""; 
echo "got to checkpoint 2";
$idir = $GLOBALS['imagepath'];  

$tdir = $GLOBALS['thumbpath'];   

$twidth = $GLOBALS['thumbw'];  

$theight = $GLOBALS['thumbh'];  

echo "got to checkpoint 3";

if(isset($_POST['uploadbtn'])) { 
echo "post submit success";

if ($_FILES['image']['error'] == UPLOAD_ERR_OK)  { 
echo "files image error line ok";


   $query = "SELECT itemid FROM stock ORDER BY itemid DESC LIMIT 1"; 
   $result = mysql_query($query); 
   $row = mysql_fetch_array($result, MYSQL_NUM); 
   $itemid = $row[0]; 

/*undefined index picture*/        $extension = explode ('.', $_FILES['picture']['name']); 
/*undefined offset 1*/        $ext = $extension[1]; 
echo $ext;
echo "above is the extention";
        $uid = mysql_insert_id(); 
        $url = $uid.'.'.$ext; // Set $url To Equal The Filename For Later Use 
        $size =  ($_FILES['image']['size'] / 1024); 

    if ($_FILES['image']['size'] < 131072) {

i know this one is a lot to ask but can someone please help me out i cant get the code to work, i have simplified it in an attempt to get a basic version working here is the new code and the errors it outputs:
