Well, I found a litle tutorial how to install PHP and GD libary from ZIP package. Here is the manual from
http://www.php.net
Installing GD extension on Windows:
First you need to download PHP 4.3.x zip package not the PHP 4.3.x installer! PHP 4.3.x zip package has extensions included already.
Follow the instructions on installing PHP at install.text.
If PHP is already working, you may now activate the GD by doing the following:
1. Uncomment the - extension_dir="". Then you should point it to where the extensions folder is located. Extensions folder is extracted from PHP zip file you downloaded.
Example: extension_dir = C:/PHP/extensions
2. Uncomment the following by removing the semicolon -
Example: extension=php_gd2.dll
3. Test if GD extension is already loaded by executing the following lines:
<?php
var_dump(gd_info());
?>
Hope this helps!
I set up PHP support to my webserver, but I can't set up that GD libary!

I did everything (I restarted server too)
extension_dir = "C:/PHP/extensions" (I try'd extension_dir = "C:\PHP\extensions" too)
extension=php_gd2.dll (Uncomented it)
But nothing!!! php_gd2.dll exists in extensions folder!! Then I Executed this code:
But then I get this error:
Fatal error: Call to undefined function: gd_info() in c:\inetpub\wwwroot\Index.php on line 2
Please help me!! What did I do wrong?? Thank you!!
