Working with the Cassini raw images

I have a cron job on one of my Unix boxes which downloads new raw
images from the Cassini site when they become available.

This means I now have on the order of two and a half thousand images, and by EoM
I'll have at least 100k.

Does anyone know of good software for managing a library of that kind of scale?
There's a description for each image, but recently NASA stopped putting in the
range information, so you can't distinguish without looking manually between
pictures of a moon filling the FoV, and navigation images with the moon three
pixels across.

Interesting ones which I've not seen very publicised are

http://saturn.jpl.nasa.gov/multimedi.../N00026567.jpg
gives an idea of the texture of the Enceladus ice fields as does N00026543.

26654 to 26682 are a mosaic of the 'boring' side of Rhea; reminiscent of Callisto.

.... N00026583.jpg is the side of Mimas away from Herschel crater, showing how
cratered the whole moon is

.... N00026544.jpg shows Rhea with a Weird Linear Feature even more pronounced than
the crack on Dione; I don't think it's a processing artefact since it appears on
images 26544 through 26550.

Enceladus encounter this week!

Since you are running on a *nix OS, MySQL/M-SQL or the like might be a
good place to store them. SQLite would be a good option also (less to
install and up-keep). You could use perl, tcl or your favorite
scripting language to store and retreive them. You may also want to
compress images before writting them out to the dB.
