If you have Gmail you can get a Firefox add on called Gspace that lets you use your empty Gmail storage as a file holding/sharing area and virtual FTP site.
Also, Googling for “online file host” comes up with lots more - and for a small number of files, I doubt it matters much where you put them.
Gspace won’t actually help you much in this scenario because you want to allow other people to access the files - that only works if you’re willing to let them have your GMail password, which I hope is something you’re not inclined to do.
