Then you got lucky.  Might not work with the very next jpeg you try, or
the next OS you're running on.  Oh yeah, I forgot, you never mentioned

4) A new symptom.  You got a server error.  Does the server error have a
number?  Or some text?

You observed something with wireshark.  What was that?  it sends the
data in a different way?  What way is that?
