I'm trying to make an blog comment script, but am having some trouble...

When a user comments on a script it updates at once using mootools by sending this parameter...

Code JavaScript:
var li = new Element('li');
var h1 = new Element('h1', {'text': response [1].get('text')}).inject(li);
var p = new Element('p', {'text': response [2].get('text')}).inject(li);

This works fine, but if I want to attach an image I dont know how to pass that along... Can somebody please help!?
