Naomi,
Thanks for the link !

There it says:

"Cameras that support raw files typically come with proprietary software for conversion of their raw format to TIFF or JPEG"

These softwares say that they can do the conversion.

PICASA - http://picasa.google.com/
IRFANVIEW - http://www.irfanview.com/


Here are some links that show how to convert NEF files

"Download Irfanview 3.97, a very capable freebie viewer with some editing features. Don't forget the set of 3.97 plug-ins. Irfanview easily handles Nikon NEF files, batch conversions of NEFs to TIFFs or JPEGs, including resizing and other tweaks during the batch processing, saves the tweaked files to the format and subfolder of your choice, and does it all pretty danged quickly."

I think InfanView is the best option, since it allows to work in batch mode.

But I've not tried yet.

Hope this helps
