Thats easy mate, stick a folder in your root (like you would images for online etc), shove the files in there, create a page with links to the files, upload, shove link to page on here. Gimme a shout if you need any help bud.
Or, if your isp allows ftp servers, you could add an anonymous user, constrain the ability to put files, and just leave get active. Or, you could open a 4shared account, upload them on there for download (saves on any bandwidth issues for your site etc)
