An image causes two variables (name_x and name_y) to be set where
these give the coordinates of the point on the image where the user
clicked. So, the corresponding x and y $_GET or $_POST variables will
be set and using your example, if you had:

<form action='adjust_cart.php' method='post'>
<INPUT TYPE="image" 
  WIDTH="20"  HEIGHT="20" style="float: right;border:0;"
  alt="Remove Product From Shopping Cart" name="remove_product" />

Then in the called script, you could use:

if (isset($_POST['remove_product_x'])){
  // do stuff to remove product from cart
