FTP Download Only

What would be the proper permissions for an FTP user so that they could only download files, but not upload or delete?

Change the permissions of the files to 644 (read-only for everybody but you) and make sure the directory is 755 (read-only for everybody but you, but still lets people in). Just make sure they’re not logging in as YOU.
