Adding images to an existing php cart

Hey everyone. I know I've posted on here before regarding this but it continues to be a thorn in my side and I haven't been able to get back to anyone because of ailing health. Now I'm at a brick wall, totally out of ideas and knowledge of how to proceed and it's holding me up going on 3 months now.  I have a site where I want to offer a few things for sale and have successfully initiated a cart after learning a little php. The problem now (and I blame lack of planning and basic stupidity...not necessarily in that order) I find a need to add a small picture to each of the items. If someone could take a moment and look at the cart I have set up and give me some idea as to how to implement this I would so be grateful. I have read that storing images on a database is not the best move so I have been trying to "call" the url from the database with no luck. I'm sorry to be a bother but I really REALLY appreciate anyone who can take a moment to help me. Thanks guys, you're the best!

here is the url to the add/cart page http://www.theblack44s.com/z/index.php

and i am attaching the cart.php file as well as posting the code here.

<?php

session_start();



$page = 'index.php';

mysql_connect("**************************","#######", "##########") or die("Couldn't connect");
mysql_select_db('b44cart') or die(mysql_error());

                                        while ($quantity_row = mysql_fetch_assoc($quantity)) {
                                                if ($quantity_row['quantity']!=$_SESSION['cart_'.(int)$_GET['add']]) {
