Hi,
whats wrong with my code.
image dosn't show in test2.php file
File: test2.php:
<img src = "test.php" />
File: test.php
session_start();
$md5_hash = md5(rand(0,999));
$security_code = substr($md5_hash, 15, 5);
$_SESSION["security_code"] = $security_code;
$width = 100;
$height = 20;
header("Content-type: image/png");
$image = ImageCreate($width, $height);
$white = ImageColorAllocate($image, 255, 255, 255);
$black = ImageColorAllocate($image, 0, 0, 0);
$grey = ImageColorAllocate($image, 204, 204, 204);
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, $grey);
imagepng($image);
imagedestroy($image);
