Thumbnail cache and the NSLU

Why is it when I access my NSLU with a directory full of images it takes forever to recompute the thumbnails? Aren't these suppose to be cached in the Thumbs.db file?

It would seem SAMBA doesn't always play nicely. http://gavinbenda.com.au/2007/10/16/windows-xp-thumbs-db-on-samba-shares/

This translates to having to perform the following on my SLUG.

-bash-3.2# pwd
/etc/samba
-bash-3.2# cat user_smb.conf
# Allow thumb.db to be created
nt acl support = no
-bash-3.2#

So now that the Thumbs.db files are being created I really don't care to see them. This requires a modification to the /etc/samba/smb.conf file the crucial line is the hide files directive.
