$string = 'PHP';

$bg = imagecolorallocate($im, 255, 255, 255);
$black = imagecolorallocate($im, 0, 0, 0);

// prints a black "P" in the top left corner
imagechar($im, 1, 0, 0, $string, $black);

For the sake of completeness, here is an example for imagechar. The base-image automatically adjusts to the size and the height of the given string. Using the rand()-function the y-position of each char is slightly varied with every loop-run. You can easily rewrite the script to use a randomly generated string - the one given here just serves as an example. <?php $string = '1 2 3 4 5 6 7 8 9 A B C D E F G'; $font_size = 5; $width=imagefontwidth($font_size)*strlen($string); $height=imagefontheight($font_size)*2; $img = imagecreate($width,$height); $bg = imagecolorallocate($img,225,225,225); $black = imagecolorallocate($img,0,0,0); $len=strlen($string); for($i=0;$i<$len;$i++) { $xpos=$i*imagefontwidth($font_size); $ypos=rand(0,imagefontheight($font_size)); imagechar($img,$font_size,$xpos,$ypos,$string,$black); $string = substr($string,1); } header("Content-Type: image/gif"); imagegif($img); imagedestroy($img); ?>
