This is a very simple php upload script with password protection..
The script is configured with an options page (options.php) and used with an upload page (index.php).
The only changes that need to be made are to create a password and change your file upload directory.
To review and change options in the script go to the "Options" page:
You can revisit options.php at any point without causing any harm. You can also just edit config.php by hand, but the password protection will only work using options.php
