the LS5000 isn't currently supported by sane.

You'll probably want to write a script/program that scans an image and
saves it to disk while the next one scans. That way, you don't need gigs
of memory but the scanner need not wait for the disk, nor the other way
around. An image scanned with the LS5000 would probably approach 60megs
or so.

In what format are they? slides? negatives?

There's a table here:
http://filmscanner.info/NikonSuperCoolscan5000ED.html

Scroll down all the way to the bottom, then up until you hit the tables.
Just a few things: 'ohne' =3D without, 'mit' =3D with, 'Bild'=3Dpicture,
'Bilder'=3Dpictures, 'Stunde' =3D hour, 'Dia' =3D slide, 'Stapel'=3Dbatch,
'Vorschau'=3Dpreview, 'Einzel'=3Dsingle, 'Belichtung'=3Dexposure. (Now you
should be able to understand the tables)
