get this message if I open the CAPTCHA generating page

 
Fatal error: Call to undefined function: imagecreate() in
c:\home\rnacarms\html\testcaptcha\captcha.php on line 6 This is the code on the captcha.php page<?phpsession_start();

$image = imagecreate(60,20);

$background_color = ImageColorAllocate($image, rand(64,70), rand(70,73),

$colour2 = ImageColorAllocate($image, rand(100,255), rand(120,255),
rand(105,255));
$colour3 = ImageColorAllocate($image, rand(131,255), rand(137,255),

imagestring($image,5,8,2,$_SESSION["captcha"],$colour1);

Just ask your web host what is supported.

Hi Tom,
I assumed that since the other PHP pages rendered OK that they do support
..php. and that perhaps there was an error on this page.
I have already sent an email asking if they do support .php and am awaiting
a reply.
I'll advise you if they say yes.
Thank you for your prompt response

Your pages seem to be working with the exception of the image being displayed. If the image is being
created on the fly, then special permissions made need to be set by your web host to allow the
script to function correctly.

Hello,

That error is caused because gdi library module is not enabled in PHP. You
will need to contact your hosting company to enable them.

Hi,
My ISP has asked if this GDI module requires a specific version of PHP, can
you help please.
They are using a Windows server
They have also offered to transfer to a UNIX server, which they say suits
..php better, my only worry is whether my "Contentseed" application will
still function OK.
Thanks in advance

Hello,

From the link I specified
"Since PHP 4.3 there is a bundled version of the GD lib. This bundled
version has some additional features like alpha blending, and should be used
in preference to the external library since its codebase is better
maintained and more stable. "

For installation in windows, from the link I specified:
"In Windows, you'll include the GD2 DLL php_gd2.dll as an extension in
php.ini. "
