I need your help in PHP4 & GD Library

Hi,
    I use PHP 4 on Windows 2000 and IIS 5.0 and all is fine.

Now I need for the images functions.

I downloaded the php_gd.dll from  http://download.swwwing.com/php4/ , copied
it to php direcotry, modified the php.ini file
extension_dir = c:\programmi\net\php\
extension=php_gd.dll

and finally restarted IIS, but PHP doesn,t recognize the images functions.

WHAT'S WRONG!?!

Please, answer me as soon as possible, I have only a few days to finish a
universitary project!!!

I have all the source codes.

If the problem is the dll and some of you has got one of it that works well,
please  send me.

THANKS IN ADVANCE


Bye
