Billede vises ikke?

Hej, jeg sidder med noget billede overlay, men kan ikke få det til at fungere.. koden ser således ud



<?php
$mysql['host'] = 'localhost'; // Host til database
$mysql['username'] = 'root'; // Brugernavn til database
$mysql['password'] = 'test'; // Kodeord til database
$mysql['database'] = 'bkv'; // Database
mysql_connect($mysql['host'],$mysql['username'],$mysql['password']);
mysql_select_db($mysql['database']);

        $sql_int_cofp = mysql_query("SELECT * FROM products where special_offer != '' order by p_id") or die(mysql_error());           
                    if ($ofp_int_row = mysql_fetch_assoc($sql_int_cofp)) {
                        $image_mad = 'images/products/'.$ofp_int_row["image"];
                       

// Overlay image
$overlay = imagecreatefrompng('images/overlay.png'); // overlay ligger i den

// The picture
$image = imagecreatefrompng($image_mad);

// select overlay color to be transparent
$white = imagecolorallocate($image, 255, 255, 255);

//
imagesettile($image, $overlay);

// Making the overlay  background transparent
imagecolortransparent($image, $white);

// Make the image repeat
imagefilledrectangle($image, 0, 0, 180, 130, IMG_COLOR_TILED);

// Output image to the browser

echo '<img src="'.$image.'" width="180" height="130" />';

imagedestroy($image);
imagedestroy($overlay);
                }


?>
