{
	var editor = ev.editor;
 	var dataProcessor = editor.dataProcessor,
	            htmlFilter = dataProcessor && dataProcessor.htmlFilter;
	            htmlFilter.addRules(
	            {
	                elements:
	                {
	                    $: function (element) {
	                         if (element.name == 'img') {
	                            if (!element.attributes['class']){
	                                	element.attributes['class'] = "helloworld";
	                            }
	                        }
