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++) {
        var body = tabBodys[j],
        id = body.getAttribute("id");
        body.onclick = function() {
            this.style.zoom = 1;
        };
        if (id != tabSrc) {
            body.style.zIndex = 1;
        } 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") {

                                //Add End================================
                                img.onload = function() {

                                    h = this.height;
                                    scale(this, 100, 120, 80);
                                    this.title = lang.toggleSelect + w + "X" + h;
                                    this.onload = null;

                                img.setAttribute("title", editor.options.imageManagerPath + ci.replace(/\s+|\s+/ig, ""));
                                img.setAttribute("width", "100px");
                                img.setAttribute("height", "100px");
 
                                del.onload = function() { //设置加载del图片时的样式
                                    this.style = "border:0";
                                    this.onload = null;
                                };
                                del.setAttribute("alt", editor.options.imageManagerPath + ci.replace(/\s+|\s+/ig, ""));
                            }
                        },
                        onerror: function() {
                            g("imageList").innerHTML = lang.imageLoadError;
                        }
                    });
                }
            }
            if (id == "imgSearch") {
                selectTxt(g("imgSearchTxt"));
            }
            if (id == "remote") {
                $focus(g("url"));
            }
        }
    }
}

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()) {
    if (!is_dir($path)) return null;
    $handle = opendir($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) {
                        $is_del = unlink($path2);
                    }
                }
            }
        }
    }
}
