My final email to him:

No. First, that “front website design” was not part of the original
project or part of the original contact. Second, it contained our
billing information and was designed to work only with our billing
system so we could not give it to you even if we had it. But since we
don’t, this is a null point.

There is no software program used to upload pictures. The application
presents a Flash user interface to upload to the Java backend. You
have all the source code for everything (including the uploading &
Flash interface). You’re Chinese business partner should be able to
see this from the code.

Please do not contact me or HTG again.

I got back the response:

Don’t be a DICK!!!!!!

That was actually the first intelligible sentence he ever wrote to me or my team.
