Thanks, Everyone:
Actually, we are placing the thumbnails in the Thumbnail bundle.  So, we
create a thumbnail (then as Admin) add it to the Thumbnail bundle of an
item, and it works fine.  But overnight our filter media runs and it
generates a thumbnail from the PDF of the item, so the next morning the
item has 2 bitstreams in the Thumbnail bundle: the jpg we added and the one
generated by filter-media from the PDF, and that generated thumbnail seems
to have precedence over our thumbnail.  It doesn't matter if I move the
thumbnail order.  However, I can delete the auto-generated thumbnail, and
our thumbnail appears (only to be replaced, again, overnight by the
filter-media).

I ma going to try Anuchit's fix of renaming our thumbnail to the name that
is used by the auto-generated thumbnail to see if that fixes the problem.
I'll know in the morning.
