Is is possible to have a php created image inside the document?

You can make images dynamically using php's Image Functions [us2.php.net].

Yes, i know that, but i want to have IN DOCUMENT (example) in a table. I don't want to have it as separate file.

<?php

header("Content-type: image/png"); //THAT IS THAT I DON'T WANT
$string = $_GET['text'];
$im = imagecreatefrompng("images/button1.png");
$orange = imagecolorallocate($im, 220, 210, 60);
$px = (imagesx($im) - 7.5 * strlen($string)) / 2;
imagestring($im, 3, $px, 9, $string, $orange);
imagepng($im);
imagedestroy($im);

You can't just output a document and an image all at once. But, you can accomplish the same thing.

What you need is a PHP script that just generates and displays the image. And then a PHP script that outputs the document, and calls the image script using <img src="whatever.php">. Now, these can be two different PHP scripts. Or, they can be the same script if the script calls itself recursively using a GET parameter.

If you're trying to generate a validation image, then you'll need a secure way for the main script to send the data to the image generation script, such as a temporary file, or a MySQL table. This isn't quite straightforward, but it can be done reliably.

There is a way that is supported only by gecko and opera but not by IE6 ; data url.

Here is an actual example with the "user profile" icon of this forum. Paste it in a test page.
