alter the references to

heading.php

and

test.tif

to reflect their location under the

dynatext

folder, as shown here:

function com_stewartspeak_replacement() {

Dynamic Heading Generator

By Stewart Rosenberger

http://www.stewartspeak.com/headings/

This script searches through a web page for specific or general elements

and replaces them with dynamically generated images, in conjunction with

a server-side script.

replaceSelector(“h1”,”dynatext/heading.php”,true);

var testURL = “dynatext/test.tif” ;

var doNotPrintImages = false;

var printerCSS = “replacement-print.css”;

var hideFlicker = false;

var hideFlickerCSS = “replacement-screen.css”;

var hideFlickerTimeout = 100;

You now need to create a PNG image file named

test.tif

in your

seophp

folder. This file

can contain anything, but it’s best if it’s as small as possible — such as a 1x1 pixel image. This

is a probe file used by the scripts for testing browser features.

test.tif

is not present, your

text won’t be replaced.

You can copy this file from the code download of this chapter.

Modify

popup.php

by adding a reference to the

replacement.js

script:

<?php

// load the popup utils library

require_once ‘include/popup_utils.inc.php’;

<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.1//EN”

“http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd”>

<html>

<head>

<title>: Table of

Contents</title>

</head>

<body onload=”window.resizeTo(800, 600);”

onresize=’setTimeout(“window.resizeTo(800, 600);”, 100);’>

<h1>: Table of Contents</h1>

12.

Load

http://seophp.example.com/popup.php

. If you followed the steps correctly and your

machine is configured with GD2 support, you should get your title replaced with an image as

shown in Figure 6-10. Compare Figure 6-10 with Figure 6-2 in order to see the difference!
