Submit Using An Image Form Processing

I am writing a shopping cart using the PayPal API. Shopping cart works. Just adding additional functionality. From the shopping cart contents I am trying to make it so the user may click on a picture of a trash can to delete the item. I wrote the following line of code: <INPUT TYPE="image" SRC="http://www.theverseoftheday.info/store-images/trash_can.png" WIDTH="20" HEIGHT="20" style="float: right;boarder: 0;" alt="Remove Product From Shopping Cart" name="remove_product" value="1" /> But when I have do: echo $remove_product; I am not getting anything. Is there a correct way of passing a variable through an image? The value in this above example is the auto_increment value of the product. From this I could remove the item from the shopping cart. OR Is there a better way to pass a variable through a graphic? I am hoping for the shopping cart contents to be just 1 form where users will have several options (change quantities, delete specific items). I can’t use a hidden field. Thank you for your help.
