1.找到uedior/dialogs/image/image.js文件，Add为修改部分的代码：
/**
* tab点击处理事件
* @param tabHeads
* @param tabBodys
* @param obj
*/
function clickHandler(tabHeads, tabBodys, obj) {
//head样式更改
for (var k = 0,
len = tabHeads.length; k < len; k++) {
tabHeads[k].className = "";
}
obj.className = "focus";
//body显隐
var tabSrc = obj.getAttribute("tabSrc");
for (var j = 0,
length = tabBodys.length; j < length; j++) {

} else {
body.style.zIndex = 200;
//当切换到本地图片上传时，隐藏遮罩用的iframe
if (id == "local") {
toggleFlash(true);
maskIframe.style.display = "none";
//处理确定按钮的状态
if (selectedImageCount) {
dialog.buttons[0].setDisabled(true);
}
} else {
toggleFlash(false);
maskIframe.style.display = "";
dialog.buttons[0].setDisabled(false);
}
var list = g("imageList");
list.style.display = "none";
//切换到图片管理时，ajax请求后台图片列表
if (id == "imgManager") {
list.style.display = "";
//已经初始化过时不再重复提交请求
if (!list.children.length) {
ajax.request(editor.options.imageManagerUrl, {

}找到uedior/php/imageManager.php文件，增加以下内容：
if ($action == "del") {
$fileName = $_POST['fileName'];
foreach($paths as $path) {
$str1 = delfiles($fileName, $path);
break;
}
}
function delfiles($fileName, $path, &$files = array()) {

$handle = opendir($path);
while (false !== ($file = readdir($handle))) {
if ($file != '.' && $file != '..') {
$path2 = $path.'/'.$file;
if (is_dir($path2)) {
delfiles($fileName, $path2, $files);
} else {
if (preg_match("/\.(gif|jpeg|jpg|png|bmp)$/i", $file)) {
$path3 = str_replace('../../', '/static/', $path2);
$fileImg = basename($path3);
if ($fileImg == $fileName) {

}
}
}
}
}
