My guess is that the content-length isn't correct for some reason. I've =
=

never used the Content-Transfer-Encoding header - perhaps the web server=
=

is encoding in some other way?

You also have Accept-Ranges, which might cause some clients to use =

multiple downloads for the one file, with some starting some way though =
=

the file. There doesn't seem to be any handling of this where you stream=
=

the file, and that would cause corruption (as asking for data from halfw=
ay =

through the file would return data from the start of the file).

Can you set the Content-Type to be image/jpeg when it's a jpeg? Probably=
=

won't help, but would be more useful for the client than =

application/octet-stream.
