I'm using imagestringup() function to write text upwards.

<?php

// incredibly, no one has added this.

// write a string of text vertically on an image..

// ;o)



$string = '(c) corz.org';

$font_size = 2;

$img = imagecreate(20,90);

$bg = imagecolorallocate($img,225,225,225);

$black = imagecolorallocate($img,0,0,0);



$len = strlen($string);

for ($i=1; $i<=$len; $i++) {

    imagecharup($img, $font_size, 5, imagesy($img)-($i*imagefontwidth($font_size)), $string, $black);

    $string = substr($string,1);

}

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

imagepng($img);

imagedestroy($img); // dudes! don't forget this!

?>
