File upload CKEditor+；KCEditor上载错误

我花了一整天的时间，但找不到解决办法。 我安装了CKEditor和KCFinder，除了一个：当我想上传文件中的图像时，dosen不上传，结果是。 当我从简单标签上传文件时，文件正在上传，但不是用拇指创建的，当我浏览服务器时，我看不到图像的图姆，只有图片和名称的图标

上传：

“上传URL”=>“http://domain.com/uploads/",
'uploadDir'=>“../../../uploads/”，

配置：

CKEDITOR.config.filebrowserBrowseUrl = '<?=$GLOBALS['_st_']['urlTree']?>libraries/kcfinder/browse.php?opener=ckeditor&type=files';
CKEDITOR.config.filebrowserImageBrowseUrl = '<?=$GLOBALS['_st_']['urlTree']?>libraries/kcfinder/browse.php?opener=ckeditor&type=images';
CKEDITOR.config.filebrowserFlashBrowseUrl = '<?=$GLOBALS['_st_']['urlTree']?>libraries/kcfinder/browse.php?opener=ckeditor&type=flash';
CKEDITOR.config.filebrowserUploadUrl = '<?=$GLOBALS['_st_']['urlTree']?>libraries/kcfinder/upload.php?opener=ckeditor&type=files';
CKEDITOR.config.filebrowserImageUploadUrl = '<?=$GLOBALS['_st_']['urlTree']?>libraries/kcfinder/upload.php?opener=ckeditor&type=images';
CKEDITOR.config.filebrowserFlashUploadUrl = '<?=$GLOBALS['_st_']['urlTree']?>libraries/kcfinder/upload.php?opener=ckeditor&type=flash';

CKEDITOR.config.filebrowserBrowseUrl='libraries/kcfinder/browse.php？opener=CKEDITOR&type=files'；
CKEDITOR.config.filebrowserImageBrowseUrl='libraries/kcfinder/browse.php？opener=CKEDITOR&type=images'；
CKEDITOR.config.filebrowserFlashBrowseUrl='libraries/kcfinder/browse.php？opener=CKEDITOR&type=flash'；
CKEDITOR.config.filebrowserUploadUrl='libraries/kcfinder/upload.php？opener=CKEDITOR&type=files'；
CKEDITOR.config.filebrowserImageUploadUrl='libraries/kcfinder/upload.php？opener=CKEDITOR&type=images'；
CKEDITOR.config.filebrowserFlashUploadUrl='libraries/kcfinder/upload.php？opener=CKEDITOR&type=flash'；

当：

$GLOBALS[''u stu']['urlTree']

在一个或多个步骤中是类似于'../'的dinamic吗
