If it is a JPEG then you should be able to use
convert pixel-vfl73.gif -resize 160x120\! jpg:pixel-vfl73.thm
However a camera may have further restrictions on the JPEG format used.
Such as size, sampling-factors, and compression-quality level
I do not believe the thumbnail is ment to be created by users as
it is probably only ment to be understood by the camera itself.
You may need to ask in some a camera specific forum for more information
about the format.
