Example with both attempts
import Ember from 'ember';
export default Ember.Component.extend({
imageLoaded: 'image loading',
imageWidth: 'width loading',
// purely to make sure image loads each time and
// is not cached for testing
volatileSrc: Ember.computed('src', function(){
return this.get('src') + '?cache=' + new Date().toISOString();

volatileSrc: Ember.computed('src', function(){
