Shell Programming and Scripting

Hi,

I want to create an image dynamically.

I used this function.

Code:

$img_handle = ImageCreate ($length, 10) or die ("Cannot Create image");

It was not creating the image. When i checked in error_log file the error was:

Code:

PHP Fatal error:  Call to undefined function ImageCreate().

I went through php ini file. Many forums have said to remove the commented line "extension=php_gd2.dll" but this line is not found.

I am using php 5.1.6 version.

I think i have to download but i don't know where and how to install and configure.

How do i download,configure and install?

With regards
Vanitha
