The default byte order is the server's byte order. You _can_ change the
image's byte_order field, and xlib will do the right thing with that (in
the sense of transmitting the bits as you pass them in). But the server
will only do the right thing with it if it was built with
MATCH_CLIENT_ENDIAN defined, which I don't think is ever the case.
Swapping client-side is the Done Thing. We could argue whether that's
philosophically correct, and it's probably not, but I think it's what
you're stuck with, sorry.
