Do you have GD installed (e.g. is it in your PHP info)? –Halil Özgür Mar 11 '11 at 15:09 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote accepted
not have the GD Library installed or it is not enabled. The GD Library is bundled with PHP, but needs to be enabled during installation. You will need Administrator rights to your server to

enable the GD Library. If you do not have Administrator access, please contact
Fatal Error: Call To Undefined Function Imagecreatefromjpeg()
your support and ask them to enable it for you. It is recommended that your GD Library version is later php install gd than gd-2.0.28. Versions older than gd-2.0.28 may not have GIF support. Versions lower than 2 do not support true color images. ======================================= Linux / Unix - Administrators (root access) ======================================= Your PHP would http://stackoverflow.com/questions/5274563/php-imagecreate-error need to be compiled with the GD Library. Here is a quote from http://www.php.net/gd "To enable GD-support configure PHP -with-gd[=DIR], where DIR is the GD base install directory. To use the recommended bundled version of the GD library (which was first bundled in PHP 4.3.0), use the configure option -with-gd. GD library requires libpng and libjpeg to compile." Please refer to the PHP manual / installation instructions https://milliondollarscript.com/article/fatal-error-call-to-undefined-function-imagecreate/ for more info. It is also possible to get pre-compiled binaries of PHP with the GD Library built in. On some systems, you will be able to install by simply typing this in: yum install gd php-gd ======================================= Windows users - Administrators ======================================= If you are hosting on Windows and have Administrator access, you can easily enable the GD Library that is distributed with PHP. Please see PHP the documentation to learn how to enable extensions in Windows. Roughly, here is what you need to do: 1. Copy the file php_gd2.dll from your PHP's ext/ directory to where you have your php extensions. (No need to copy if php_gd2.dll is in the extension dir already. Look in php.ini for 'extension_dir' directive to find what is your current extension directory) 2. Modify your php.ini and change the following line: ;extension=php_gd2.dll to: extension=php_gd2.dll 3. Restart your web server. Posted in Technical Support.

the code is always incorrect, make sure to download the Securimage Test Script, upload it to your website, and open the URL in your web browser.
The test script checks for configuration errors in PHP than can cause Securimage not to work, as well as makes sure your server meets the requirements for using Securimage. I get an error that says "Call to undefined function imagecreate()" in securimage.php. Even if I type the correct code, Securimage always says it is wrong. I get an error that says "Call to undefined function imagecreatetruecolor()" in securimage.php. I get an error that says "Call to undefined function imagettftext()" in securimage.php. The image appears but there is no text on the image. The image does not show up on my HTML page. No image appears and nothing shows up when I go to securimage_show.php I get an error saying "Warning: include(securimage.php) [function.include]: failed to open stream: No such file or directory in …" I get an error on my pages that says "Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at page.php:###) in securimage.php on line ###." I get an error saying "Parse error: parse error, unexpected T_CONST, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’" All Questions I get an error that says "Call to undefined function imagecreate()" in securimage.php. AnswerIf this error appears it means PHP does not have GD support which is required for creating images with PHP. Unfortunately, if you get this error Securimage will not work. GD has been included with PHP since version 4.3 but some older PHP installations do not support it. You will need to contact your webhost to request GD support, or recompile PHP with GD support if you are running Securimage on your own server. See the Installing/Configuring GD page on php.net for more information. Even if I type the correct code, Securimage always says it is wrong. AnswerIf you have not already done so, please download the Securimage Test Script and follow the directions listed at the top of this FAQ page. Otherwise follow the steps below. 1. In your form processor, the first line of the script must beIf any HTML or whitespace is output before starting the PHP session, then the validation will not work. 2.
