Here is the php script to generate your own powerball numbers using php and gd:
createimage.php

$pb_bg_image = imagecreate(380, 75)
      or die('Cannot Initialize new GD image stream');
$pb_bg = imagecolorallocate($pb_bg_image, 255, 255, 255);
$white = imagecolorallocate($pb_bg_image, 255, 255, 255);
$gray = imagecolorallocate($pb_bg_image, 185, 185, 185);
$red = imagecolorallocate($pb_bg_image,255,0,0);
$black = imagecolorallocate($pb_bg_image,255,50,50);
imagefilledarc($pb_bg_image, 28, 38, 58, 54,  0, 360, $gray,IMG_ARC_PIE);
imagefilledarc($pb_bg_image, 30, 38, 50, 50,  0, 360, $white,IMG_ARC_PIE);
imagefilledarc($pb_bg_image, 92, 38, 58, 54,  0, 360, $gray,IMG_ARC_PIE);
