How to upload images to MySql database.

Question

Hey guys so i created a insert form in dreamweaver to add to a database, its workin fine but i want to add another field to browse for and add a small image of the item. I created my insert form with a wizard and I'm not sure how to add an image uploader to it. I have a blob field in my database called "image" I'm just not sure how to add to it from my form.  Here is the code for my insert page so far:
<?php require_once('../Connections/cbdb.php'); ?>
<?php require_once('Zend/Date.php'); ?>
<?php
if (!isset($_SESSION)) {
  session_start();
$MM_authorizedUsers = "";
$MM_donotCheckaccess = "true";
// *** Restrict Access To Page: Grant or deny access to this page
function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) {
  // For security, start by assuming the visitor is NOT authorized.
  $isValid = False;
  // When a visitor has logged into this site, the Session variable MM_Username set equal to their username.
  // Therefore, we know that a user is NOT logged in if that Session variable is blank.
  if (!empty($UserName)) {
    // Besides being logged in, you may restrict access to only certain users based on an ID established when they login.
    // Parse the strings into arrays.
    $arrUsers = Explode(",", $strUsers);
    $arrGroups = Explode(",", $strGroups);
    if (in_array($UserName, $arrUsers)) {
      $isValid = true;
    // Or, you may restrict access to only certain users based on their username.
    if (in_array($UserGroup, $arrGroups)) {
      $isValid = true;
    if (($strUsers == "") && true) {
      $isValid = true;
  return $isValid;
$MM_restrictGoTo = "login.php";
if (!((isset($_SESSION['MM_Username'])) && (isAuthorized("",$MM_authorizedUsers, $_SESSION['MM_Username'], $_SESSION['MM_UserGroup'])))) {  
  $MM_qsChar = "?";
  $MM_referrer = $_SERVER['PHP_SELF'];
  if (strpos($MM_restrictGoTo, "?")) $MM_qsChar = "&";
  if (isset($_SERVER['QUERY_STRING']) && strlen($_SERVER['QUERY_STRING']) > 0)
  $MM_referrer .= "?" . $_SERVER['QUERY_STRING'];
  $MM_restrictGoTo = $MM_restrictGoTo. $MM_qsChar . "accesscheck=" . urlencode($MM_referrer);
  header("Location: ". $MM_restrictGoTo);
  exit;
?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

      break;
    case "date":
      if ($theValue == "")
    $theValue = "NULL";
   else
    $zendDate = new Zend_Date($theValue, "d/M/yyyy");
    $theValue = "'" . $zendDate->toString("yyyy-MM-dd") . "'";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  return $theValue;
// *** Redirect if username exists
$MM_flag="MM_insert";

Storing images in a database is generally not a good idea. Apart from bloating your database and increasing the risk of table fragmentation when images are updated or deleted, you cannot display an image directly from a database. However, if you want to do it, you will find instructions here: http://cookbooks.adobe.com/post_Upload_images_to_a_MySQL_database__PHP_-16609.html.
The more common (and efficient) approach is to use the database to store details of the image, such as filename and caption. Then upload the image to your website's file system.
I give step-by-step instructions how to do this in my book, "Adobe Dreamweaver CS5 with PHP: Training from the Source", but if you have reasonable skill at using PHP, you can learn how to handle file uploads from the PHP Manual at http://docs.php.net/manual/en/features.file-upload.php.
