Ah yes, I'll just tell my mom to write an XML-parsing script to move the files around in case she ever changes her setup. ;)

And even Finder quicklook seem to render the full .jpegs just fine and fast enough, so wasting so much disk space on a useless preview/thumbnail feature (to me) is a dealbreaker. I'd even be willing to accept missing or postage stamped thumbnails, rather than having to uninstall applications and remove music to make room for my photos.
