Installation is a breeze🙂 First of all, you mentioned you grabbed zlib113.zip, gd-1.8.4.zip, and lpng1011.zip...... you don't need them unless you want to compile your very own custom copy of php_gd.dll. This can be a real pain on 'Doze unless you really know what you're doing. It's much easier to use the pre-compiled binaries from php.net. If you installed PHP using the Win32 installer, you need to download the zip package from php.net. If you installed using that zip package, you already have GD. Here's the steps (once you've downloaded the zip🙂:
1) Create a directory called "extensions" within the folder (c:\php4 for example) you installed PHP in.
2) Check to make sure that php_gd.dll is in that extensions directory. If it's not, extract it from the zip package you grabbed off php.net and put it there.
3) Edit php.ini, add the following directive:
extension_dir = "c:/php4/extensions/"
Change "c:/php4" to reflect your setup. Note the use of forward slashes. Also note the trailing slash.... it must be there or you'll get errors.
4) Add, or uncomment, the following line (also in php.ini):
extension=php_gd.dll
5) Restart your webserver.
GD should now be happily waiting for you to create some images. To test, call phpinfo(). There should be GD section in the output. HTH.
