Just tried it with the following but still fails. All I'm getting is a blank
page.
<php?
function create_image()
{
//Let's generate a totally random string using md5
$md5_hash = md5(rand(0,999));
//We don't need a 32 character long string so we trim it down to 5
$security_code = substr($md5_hash, 15, 5);
//Set the session to store the security code
$_SESSION["security_code"] = $security_code;
//Set the image width and height
$width = 100;
$height = 20;
//Create the image resource
$image = ImageCreate($width, $height);
//We are making three colors, white, black and gray
$white = ImageColorAllocate($image, 255, 255, 255);
$black = ImageColorAllocate($image, 0, 0, 0);
$grey = ImageColorAllocate($image, 204, 204, 204);
//Make the background black
ImageFill($image, 0, 0, $black);
//Add randomly generated string in white to the image
ImageString($image, 3, 30, 3, $security_code, $white);
//Throw in some lines to make it a little bit harder for any bots to break
ImageRectangle($image,0,0,$width-1,$height-1,$grey);
imageline($image, 0, $height/2, $width, $height/2, $grey);
imageline($image, $width/2, 0, $width/2, $height, $grey);
//Tell the browser what kind of file is come in
header("Content-Type: image/jpeg");
//Output the newly created image in jpeg format
ImageJpeg($image);
//Free up resources
ImageDestroy($image);
}
create_image();
