Post subject:  Dynamic image problem - why doesnt it save as a png?

Hi all!

I made a dynamic image generator that doesnt seem to work porperly. This dynamic image generator takes user input (i.e. choosing their desired font-type, image, and text). It generates the picture perfectly but when I saved it ("Save Picture As..."); it saves as a html file not a png file.

Here is the PHP code:

$text = $_POST['add_text'];
$font_type = $_POST['font_type'];
$ul_image = $_POST['ul_image'];

$im = imagecreatefrompng("$ul_image");

$width = imagesx($im);
$height = imagesy($im);


if($font_type == "image/font01.TTF"){
  $font = 8;
else if($font_type == "image/font02.TTF"){
  $font = 9;
else if($font_type == "image/font03.TTF"){
  $font = 7;

$font_colour = ImageColorAllocate ($im, 255, 255, 255);
$arr = imagettfbbox($font, 0, $font_type, $text);

$lower_left = $arr[1];
$lower_right = $arr[2];

$var = $lower_left + $lower_right;

$leftTextPos = ($width - $var) - 5;

ImageTTFText($im, $font, 0, $leftTextPos, $height-5, $font_colour, $font_type, $text);

Header('Content-type: image/png');




And here is the html Code:

<form action="image.php" method="post">
<select name="ul_image">
<option value="image/image1.PNG">image1</option>
<option value="image/image2.PNG">image2</option>
<option value="image/image3.PNG">image3</option>
<option value="image/image4.PNG">image4</option>
<option value="image/image5.PNG">image5</option>
<select name="font_type">
<option value="image/font01.TTF">Font 01</option>
<option value="image/font02.TTF">Font 02</option>
<option value="image/font03.TTF">Font 03</option>
<input type="text" maxlength="22" name="add_text">

<input type="submit" value="submit">

I can however, save a dynamic image as a png file if there are no user input. :?

What did I do wrong? Is there anything missing or something out of place? Any sort of help would greatly be appreciated. :cry:
