I don't think that there is anything you can do to incite Google to index your images. Furthermore, the Google image database is seldomly updated. It is my experience that it can take a long time before the images from a new site get indexed, and one year or more is unfortunately not unusual. Just watch your logs for the Googleimage bot. Once you see it, you'll be in at the next update.
