Greetings, We are able to edit image characteristics with this particular get_image_tag filter if we are adding images,but can there be any similar filter or action that may we use to edit these characteristics when publish is added or edited - up-to-date?

This is actually the link I discovered.

Thanks ahead of time.

Yes, use image_send_to_editor.
