Program to create/update Windows 'thumbs.db' files?

[Modulok]

List,

Is there a program for BSD/linux which will walk a directory tree and
create/update the Windows, 'thumbs.db' files? Something quite the
opposite of vinetto.

I was thinking of doing this on one of our media servers. I'd put said
command in a cron job. Network clients would have faster access to
thumbnails. Everybody is happy. BUT! I can't let the clients do this
themselves, as these network shares are strictly read-only. I don't
really want to sit at a windows computer for the rest of eternity
clicking each folder in turn and waiting for the thumbs file to
update. Just thought there might be something already out there to do
this.

Thanks! Happy new year everyone.
