After some digging (and more reading BitmapAjaxCallback) I have come up with this solution:
BitmapAjaxCallback cb = new BitmapAjaxCallback();
cb.header("Referer", "http://www.example.com");
cb.url(MyApplication.MEDIA_BASE_URL + getItem(position)).fallback(R.drawable. default_image).memCache(true).fileCache(true);
new AQuery(submodelPhoto).image(cb);
Seems to work, just wish I could find an approach that would set the referrer for AQuery for every request.
