GD with Freetype support is the requirement for the internal CAPTCHA. </p> https://www.machform.com/forums/topic/how-to-create-first-captch#post-3778 Sun, 23 Nov 2008 06:08:49 +0000 zoomer 3778@https://www.machform.com/forums/ <p>Just a note, I did everything above but still couldn't see the Captcha letters, only the text box to fill in the letters. I finally learned that I was missing "freetype support" which I had to have my server install. Once they did this, everything worked fine. </p> https://www.machform.com/forums/topic/how-to-create-first-captch#post-3721 Tue, 18 Nov 2008 16:40:56 +0000 SchaefferMarc 3721@https://www.machform.com/forums/ <p>THANKS !!!</p> <p>After unzipping the "php_gd2.dll" into the "/ext"-folder and modifying the php.ini by adding under the section "Dynamic Extensions" "extension=php_gd2.dll" it works.</p> <p>Thank you again for your support. </p> https://www.machform.com/forums/topic/how-to-create-first-captch#post-3670 Fri, 14 Nov 2008 23:18:45 +0000 redityo 3670@https://www.machform.com/forums/ <p>Hi,</p> <p>It seems you installing PHP module with installer package, try to download PHP ZIP package the "php_gd2.dll" module should be in "/ext" folder. </p> https://www.machform.com/forums/topic/how-to-create-first-captch#post-3660 Fri, 14 Nov 2008 16:09:16 +0000 SchaefferMarc 3660@https://www.machform.com/forums/ <p>Hi redityo,</p> <p>it's on my own win2003 server with php 5.2.6, but I got no php_gd2.dll.. </p> https://www.machform.com/forums/topic/how-to-create-first-captch#post-3647 Thu, 13 Nov 2008 22:26:57 +0000 redityo 3647@https://www.machform.com/forums/ <p>Do run your own server ? it's so if your server run on windows, you can check on your /php/ext or /php/extension directory for php_gd2.dll file. If it's exist you can put these line to your php.ini</p> <pre><code>extension=php_gd2.dll</code></pre> <p>if you run on linux, I'm afraid there are some steps you have to do.

Please confirm with your host regarding this, they might have it disabled.</p> <p>Meanwhile, you can always use the reCaptcha.
