It might be easier to debug if you saved the dynamic image to a new file "dynamic.php" and use that as the source for the image as in

or you could try this

echo the header as the first instruction in square() and

echo '<img src="' . $show->square .'">';

but I prefer using the first method.

Lose all the HTML. You're sending an image, not an HTML page. PNG files do not start with "<html>"; they start with PNG and anything else is corruption.

thanks for the replys but it still doesnt work, here is the code i am using now, with 2 files. i took out all HTML tags but that didnt help

class dshape.php

<?
require "shape_cls.php";
header ("Content-type: image/png");

$show = new shape();

$show->square();
?>

class shape_cls.php

class shape{
function square(){

$img_handle = ImageCreate (20, 230) or die ("Cannot Create image");
$back_color = ImageColorAllocate ($img_handle, 0, 10, 10);
$txt_color = ImageColorAllocate ($img_handle, 233, 114, 191);
ImageString ($img_handle, 31, 5, 5, "My first Program with GD", $txt_color);
ImagePng($img_handle);

imagedestroy($img_handle);

}
}
?>
