سلام و خسته نباشید

از fck editor استفاده کردم در پروژه ام نیاز دارم که عکس آپلود کنم از طریق آن

سرچ کردم تغییرات رو در فایل FredCK.FCKeditorV2.FileBrowser.Config  اعمال کردم  اما وقتی عکس ارسال می کنم خطا میده که فرمت فایل صحیح نیست.دیباگ هم کردم اما متوجه نشدم.  لطفا پاسخ بدین.

تنظیمات فایل رو به صورت زیر قراردادم.

<%@ Control Language="C#" EnableViewState="false" AutoEventWireup="false" Inherits="FredCK.FCKeditorV2.FileBrowser.Config" %>

<script runat="server">

    private bool CheckAuthentication()
    {

        if (Session.Count > 0)
        {
            return true;

        }
        return false;
    }

    public override void SetConfig()
    {

        Enabled = CheckAuthentication();
