<?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!
