I found this script wasn't as useful as I had hoped, because
looking only at thumbnails doesn't show me enough detail to let
me decide which of a few redundant images I should keep, etc.

In the meantime I found a nice lightweight image viewer that I am
using as a replacement for xv: qiv [1] (quick image viewer).

It has a nice feature where if you press 0-9, it runs
'qiv-command n foo.jpg', so I wrote a simple 'qiv-command' script [2]
that lets me rescale the current displayed image to some smaller
size if I don't want to keep the original 4 megapixel one around.

It uses another script I wrote, resize-images [3] to do the resizing.
Unfortunately it doesn't rewrite the internal exif metadata yet :(

Note that this and the edit-images script I wrote about before
are used to rescale the *original* image before it gets archived
on my site, not to make thumbnails etc for publication; I use
make_variants [4] for that. (why not just keep all the originals
around? Because they're about 2 megs each, which would be ~12G/yr
at the rate I shoot pics)

This stuff is still way too complicated and poorly-documented,
but my own publishing process is gradually getting better.

Tonight I'm going to a local linux user group meeting [5] to listen
and maybe talk a bit about linux and digital photography; should be
fun/useful.
