PHP:5.5.11 OS: CentOS (5.11) i think it is server related issue any ideas ? i thought the problem is with the GD Libraries... but also they show as installed and running fine
<?php

session_start();
// Generate the 5 digits string
$text = rand(10000,99999);

$_SESSION['captcha'] = $text;
// Define the Image Height & Width
$width = 75;
$height = 37;
// Create the Image
$image = imagecreate($width, $height);
// Set the background color

imagestring($image, $font_size, 15, 10, $text, $white);
imageline($image, 0, mt_rand(5, $height-5), $width, mt_rand(5, $height-5), $white);
imageline($image, mt_rand(10, $width-10), 0, 0, mt_rand(10, $width-10), $white);
// Output the $image, don't save the file name, set quality
