It's simple -- just store your home page's HTML pages, images, etc., on the FTP server, and give out your FTP address just like a HTTP address.
For example, if you stored your home page welcome page at the following path on your FTP server:
/users/bob/welcome.html
and if your FTP server's domain name is my_university.edu, your home page address would be:
ftp://my_university.edu/users/bob/welcome.html
