Dear mate,

I think this what you are looking for

The contact form with CAPTCHA

<form method="POST" name="contact_form"
action="<?php echo htmlentities($_SERVER['PHP_SELF']); ?>">

<label for="name">Name: </label>
<input type="text" name="name"
value="<?php echo htmlentities($name) ?>">

<label for="email">Email: </label>
<input type="text" name="email"
value="<?php echo htmlentities($visitor_email) ?>">

<label for="message">Message:</label>
<textarea name="message" rows=8 cols=30
><?php echo htmlentities($user_message) ?></textarea>

<img src="captcha_code_file.php?rand=<?php echo rand(); ?>"
id="captchaimg" >
<label for="message">Enter the code above here :</label>
<input id="6_letters_code" name="6_letters_code" type="text">

<input type="submit" value="Submit" name="submit">
</form>

The HTML form above contains the fields for name, email and message. In addition, we have the CAPTCHA image. The <img> tag for the CAPTCHA image points to the script captcha_code_file.php. The PHP script in ‘captcha_code_file.php’ creates the image for the captcha and saves the code in a session variable named ‘6_letters_code’.
