As far as I know, and I’ve researched the topic a lot, there’s no hook to do this. Neither an easy jQuery. And looking at WordPress 3.5 beta-1, all previous hacks and hooks may be obsolete soon or just after soon…
I wonder if you want to modify the HTML of the inserted image, with the image_send_to_editor or get_image_tag filters?
