I have used a simple verification image for an equally simple contact form for quite a while now, and as basic as it is, I have never seen any spam from it yet. Recently, though, it has broke.
I have two sites hosted with Supanames, and both sites have this problem, though a site hosted elsewhere is fine, so I am guessing it is something the host has changed on the server (they WERE working fine). GD is installed and working, and both the broken sites and the working site are running on the same version of PHP.
THIS is one of the broken examples.
THIS is the working example.
Code: Select all
<?php
header('Content-type: image/jpeg');
$width = 50;
$height = 24;
$my_image = imagecreatetruecolor($width, $height);
imagefill($my_image, 0, 0, 0xFFFFFF);
for ($c = 0; $c < 40; $c++){
$x = rand(0,$width-1);
$y = rand(0,$height-1);
imagesetpixel($my_image, $x, $y, 0x000000);
}
$x = rand(1,10);
$y = rand(1,10);
$rand_string = rand(1000,9999);
imagestring($my_image, 5, $x, $y, $rand_string, 0x000000);
setcookie('tntcon',(md5($rand_string).'a4xn'));
imagejpeg($my_image);
imagedestroy($my_image);
?>Cheers guys!
