Where did you see QImage needs a windowing server ?
Which QPA plugin are you using for headless apps ?

QGuiApplication should work fine for command-line-only apps, just use
a QPA plugin that doesn't require a window system, try the offscreen
plugin.

A good example of a gui app running on headless server is PhantomJS,
which runs the entire QtWebKit stack.
