How do I display an image? - Mailing list pgsql-php

Fairly new to PHP.  How do I display an image I have stored in my db?  I
found code on phpbuilder.com, but I must be doing something wrong. If I
just print out the field, it prints the machine code immediately.  But I
alas my users want an image instead of machine language.

CREATE TABLE mdc_imageref (
  keyp_imageref int4,
  modid int8,
  img bytea,
  keyf_image int4
)


$id = $_GET["id"];
if($id) {
     $db = db_connect();
     $result = pg_query($db,"Select ir.img,p.keyp_products
                    from mdc_products p join mdc_product_images pi on
p.keyp_products = pi.keyf_product
                    join mdc_attributes a on a.keyp_attribute =
pi.keyf_attribute
                    join mdc_images i on i.keyp_images = pi.keyf_image
                    join mdc_imageref ir on ir.keyf_image = i.keyp_images
                    where p.keyp_products = $id and keyp_attribute = 7");
         $row =  pg_fetch_array($result);
         $type = "JPG";
         Header( "Content-type:$type");
         echo $row[0];
}
