So what I've decided is that maybe I can break everything down into zip files, grouped by designer or version or something, and have the site itself act as a thumbnail gallery, with a bunch of smallish Torrent links to get the covers themselves.
The goal is to have everything all in one place, easily navigatable, and avoiding the trouble of having to browse through 50+ pages of off-tangent messages to find anything.
Anybody who has suggestions should offer them now. Or if anybody would like to come forward with the URL of that image hosting site I read about in passing a few days ago (and promptly forgot), the one that hosts images bigger than 1 meg, that would probably solve all the problems right there.
Thanks guys!
