Hey guys, im trying to create a 'captcha' image for registration security for my site. currently i have 2 separate pages working together, my captcha.php file & my register.php now, what i am doing is trying to get a generate code that will be random and create an image with this string. this image will then be linked in the registration form where the user will have to match that random string image. sounds simple except , for some reason the code i have supplied from the tutorial is not outputting the image in the form. i have GD's installed on my server, and i have the font file saved also in the directory/ my code is : captcha.php <?session_start(); header('Content-type: image/jpeg'); $text = $_SESSION['secure']; $font_size = 30; $image_height = 200; $image_width = 40; $image = imagecreate($image_width, $image_height); imagecolorallocate($image, 255, 255, 255); // white $text_color = imagecolorallocate($image, 0, 0, 0); //black imagettftext($image, $font_size, 0, 15, 30, $text_color, 'font.ttf', $text); imagejpeg($image); ?> so in this i have created the image captcha.php should now be a jpeg.. i then go to my register.php declare the $_SESSION and input the src="captcha.php'' register.php <?php include('include/init.php'); $_SESSION['secure'] = rand(1000,9999); ?> and the form : <tr> <td class="register_td_left2"><span class="">Security Code:</span></td> <td valign="middle" style="padding-left:2px"><input id="security_code" name="security_code" type="text" maxlength="4" size="5"></td> <td align="left" valign="middle"><img src="generate.php" alt="Your Security Code"></td> </tr> this is my first time adding a captcha and going through this process. the only thing i can think that would not be allowing it output the image, would be the 'font.tff' not properly working, or for some odd reason i dont have the GD functions installed correctly. any suggestions ? or ideas ?
