Hi friends,
I had to develope a script where some text needed to written on a base image depending on the
session variables.
I have come up with a code that would give you an idea on the GDLib functionality of PHP. This is a
very basic example that helps you in creating a small application that would write to an image
(PNG).
Hope this helps someone.
Thank you,
Sri.
PSS: I don't think there should be any problem with the code, if incase you happen to find some
problem let me know. I'll be glad to help you.

header("Content-type: image/png");
$string = $HTTP_POST_VARS['caption'];
$im = imagecreatefrompng("meditate.png");
$orange = imagecolorallocate($im, 220, 210, 60);
$px = (imagesx($im) - 7.5 * strlen($string)) / 2;
imagestring($im, 9, $px, 9, $string, $orange);
imageline($im,$px,30,$px+9.0*strlen($string),30,3);
imagedashedline($im,$px,36,$px+9.0*strlen($string),36,3);
imagepng($im);
imagedestroy($im);
