Hello
what you normally do would be to store the name of the image, so product1.jpg thats all you store then when you create the php loop to call the other product information you like name description you also call the image put filling in the missing info like <img scr="images/<?php code here ?>" />
Many ways to do it to be honest, to display the picture that is. In dreamweaver i am unsure as i do not use most people wont as i have gathered you understand by the comment you made. But something like this can do it in PHP
$query = mysql_query("SELECT * FROM img");
while($row = mysql_fetch_array($query)){
echo $row['image'];
Hand coding is simpler, but you would need to make the array contain all the information for each product like name, description, image, price ...
I hope this helped a little
