My Captcha Code:

 

<?php
//Start the session so we can store what the code actually is. 
session_start(); 

//Now lets use md5 to generate a totally random string 
$md5 = md5(microtime() * mktime()); 

/* 
We dont need a 32 character long string so we trim it down to 5 
*/ 
$string = substr($md5,0,5);


/*
Now for the GD stuff, for ease of use lets create 
the image from a background image. 
*/ 

$captcha = imagecreatefrompng("./captcha.png"); 

/* 
Lets set the colours, the colour $line is used to generate lines. 
Using a blue misty colours. The colour codes are in RGB 
*/ 

$black = imagecolorallocate($captcha, 0, 0, 0); 
$line = imagecolorallocate($captcha,233,239,239); 

/* 
Now to make it a little bit harder for any bots to break,  
assuming they can break it so far. Lets add some lines 
in (static lines) to attempt to make the bots life a little harder 
*/ 
imageline($captcha,0,0,39,29,$line); 
imageline($captcha,40,0,64,29,$line);


/* 
Now for the all important writing of the randomly generated string to the image. 
*/ 
imagestring($captcha, 5, 20, 10, $string, $black); 


/* 
Encrypt and store the key inside of a session 
*/ 

$_SESSION['key'] = md5($string); 

/* 
Output the image 
*/ 
header("Content-type: image/png"); 
imagepng($captcha);


?>

Didnt notice u wrote about the red x. The source of the image should be src and not xsrc:

 

<img src='captcha.php' border="0">

[Fadion]

Or if that doesnt work, try changing:

 

this

imagecreatefrompng("./captcha.png");

 

to:

imagecreatefrompng("captcha.png");
