方法:
一.将ckfinder文件夹copy至/fckeditor/editors/目录下.
二.修改fckconfig.js中的打开路径为:

FCKConfig.LinkBrowserURL = FCKConfig.BasePath+'ckfinder/ckfinder.html';
FCKConfig.ImageBrowserURL =FCKConfig.BasePath+ 'ckfinder/ckfinder.html?type=Images';
FCKConfig.FlashBrowserURL = FCKConfig.BasePath + 'ckfinder/ckfinder.html?type=Flash';
FCKConfig.LinkUploadURL = FCKConfig.BasePath + 'ckfinder/core/connector/aspx/connector.aspx?command=QuickUpload&type=Files';
FCKConfig.ImageUploadURL = FCKConfig.BasePath + 'ckfinder/core/connector/aspx/connector.aspx?command=QuickUpload&
FCKConfig.FlashUploadURL = FCKConfig.BasePath + 'ckfinder/core/connector/aspx/connector.aspx?command=QuickUpload&
三.修改ckfinder目录下的config.ascx.设置默认上传路径
        BaseUrl = "/uploads/";
        BaseDir = "/uploads/";
