I would kindly suggest that instead of showing an obscene image, that you should just have an image that says something like:
Dear Google Employee:
This image was stolen from MY website at mydomain.com
There's also the classic Not Nice remedy used against incurable hotlinkers in general: redirect to some lunatic-fringe political site's main page. The target site will be happy for the traffic and will not inquire further, and the hotlink will be gone before you can blink. But it has to be something extreme. In the present case, not something boring like Amnesty International but some absolutely over-the-top China-loathing site.
