i would like to make scaled images through imagecopyresampled but i dont know how to use the gdlibrary... i dont know how to install it in the first place... help
The GD library needs to be compiled into your version of php. You can't simply "install" it. Can't say much more without knowing your setup: what operating system are you running, how did you originally install php, etc.
If you are running on windows then all you need to do is go into your php.ini file and uncomment (remove the # from) the line #extension=php_gd2.dll Then restart your apache server and bobs your aunty.
