I actually don't think Mythweb has much to do with it; it's a more
general Apache problem. My Apache server won't serve *any* images off
of an SMB share without that configuration change; they all come back as
0-length files. I had never noticed it before because I never really
tried to get thumbnails working on my MythVideo share before 0.21; there
was no good interface for it in MythWeb until then, and setting them up
by hand was just too much work. ;)
Here's the official Apache documentation about it:

It works for me but I'd like to see the original poster try it. I
disabled it in the main server configuration, but it might be sufficient
to disable it for the directories that MythWeb serves thumbnails from.
