Explaining the show sub-directories

+| Dave | The issue is that, although we started with show "assets" as
+`ROOT/eps/hpr1234_picture1.jpg` and the like, it was decided that we'd make a
+sub-directory per show for such things: `ROOT/eps/hpr1234/picture1.jpg`. Then
+because the web server is set to allow directory browsing (I think I have this
+right) we realised we needed an `index.html` in that directory. I create these
+as a list of the URLs of all the assets in the sub-directory, pictures, long
+notes, etc. I do this when preparing pictures for shows I process as well.
+
+However, there's no guarantee that all shows with assets are set up with an
+`index.html` if it might be needed.
+
+The placement of assets for shows is duplicated on the IA - or is in the
+process of being copied over.
+
+Actually, I'm not clear why we allow directory browsing anyway, I thought most
+web servers could turn this off (caveat: I used to be a web admin but in the
+*very* early days, and my knowledge may be past its sell by date).

 Do we still need this page? If so, it has broken image links, and broken permalinks (i.e. https://www.hackerpublicradio.org/show.php?ep=300)
