1.后台图片上传路径/Public/kindeditor/php/upload_json.php;
2.createHtml方法改为如下: 
 
function createHtml(){
		editor = KindEditor.create('#content{$nodeType}', {
				safeMode: true,
				resizeType: 1,
				allowFileManager: true,
				allowPreviewEmoticons: false,
				items: [
				'source','fontname', 'fontsize', '|', 'forecolor', 'hilitecolor', 'bold', 'italic', 'underline',
				'removeformat', '|', 'justifyleft', 'justifycenter', 'justifyright', 'insertorderedlist',
				'insertunorderedlist', 'image', 'multiimage'],
				afterUpload : function(url, data, name) { //上传文件后执行的回调函数,必须为3个参数
					if(name=="image" || name=="multiimage"){ //单个和批量上传图片时
						var img = new Image(); img.src = url;
						img.onload = function(){ //图片必须加载完成才能获取尺寸
							if(img.width>330) editor.html(editor.html().replace('<img src="' + url + '"','<img src="' + url + '" width="330"'))
						}
					}
				}				
			}
		);
	}
