Following up on this, I understand how this works for _new_ images that I add to a document: my document listener will receive a DOM mutation event for each newly inserted image, at which point I can add my click listener. However, what happens if I'm loading a document with existing images? I'd like the existing images (in addition to new images that I add to the document) to have click handlers as well. Apologies if I'm just missing something obvious here!
