Using your FTP program, connect to your web server and create a directory to store your scripts. Then upload the files using the directory structure they are in. Make sure you upload the files in binary mode (check the settings of your FTP program). Please note that uploading in ASCII mode can lead to uncommon errors (e.g. 'class not found' error during installation), also images may not be uploaded correctly.
