In writingOverImage.php you cannot have your html/form and the php code for creating the image in the same file. They must in separate files like so

form.php

<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Floating window with tabs</title>
 
<style>
 
/*
This defines the workspace where i place the demo.
*/
#container {
    text-align: left;
    background: #FFF;
    width: 865px;
    margin: 20px auto;
    padding: 20px;
    border-left: 1px solid #CCC;
    border-right: 1px solid #CCC;
    -moz-box-shadow: 0px 0px 10px #BBB;
    -webkit-box-shadow: 0px 0px 10px #BBB;
    box-shadow: 0px 0px 10px #BBB;
}
</style>
         
</head>
<body>
 
 
<div id="container">

<?php 
    if($_POST["sending"]=="yes"){
        if(strlen($_POST["text"]<50)){
            echo '
                <img id="imgFinal" src="writingOverImage.php?size=50&text='.$_POST["text"].'" />
 
                <img id="imgFinal" src="writingOverImage.php?x=right&y=center&size=30&r=74&g=50&b=170&text='.$_POST["text"].'" />
 
                <img id="imgFinal" src="writingOverImage.php?x=left&y=bottom&size=90&text='.$_POST["text"].'" />
            ';
        }
        else{
            echo "The text is too large for my demo!! ";
        }
    }
    else{
        echo '
            <img id="imgFinal" src="writingOverImage.php?size=50&text=Hello world!!" />
        ';
         
    }
?>

<form name="formulario" action="" method="post" class="contactoFormulario">
        <div class="caja"><input type="text" name="text" />Text you want to write over the image</div>
 
        <button class="botonFormulario" type="submit" name="Submit" value="Enviar" />Generate image</button>
        <input type="hidden" name="sending" value="yes" />
    </form>
</div>
 
</body>
</html>

writingOverImage.php

<?php
require_once 'class.textPainter.php';

$x = $y = $R = $G = $B = null;

if(isset($_GET['x'], $_GET['y']))
{
   $x = $_GET["x"];
   $y = $_GET["y"];
}

if(isset($_GET['r'], $_GET['g'], $_GET['b']))
{ 
    $R = $_GET["r"];
    $G = $_GET["g"];
    $B = $_GET["b"];
}

$size = $_GET["size"];
$text = $_GET["text"];
 
 
$img = new textPainter('./imgs/writingOverImage.jpg', $text, './Franklin.ttf', $size);
 
if(!empty($x) && !empty($y)){
    $img->setPosition($x, $y);
}
 
if(!empty($R) && !empty($G) && !empty($B)){
    $img->setTextColor($R,$G,$B);
}
 
$img->show();

NOTE: if your are using PHP version 5.3 or newer then your need to make the following changes to class.textPainter,php.

Line 78 needs to be changed to

                imagejpeg($this->img, NULL, $this->jpegQuality);

Line 154 needs to be changed to

    	$this->format = preg_replace("/.*\.(.*)$/","\\1",$this->imagePath);
