using (SPSite oSPsite = SpSecurityHelper.GetElevatedSite(GetSiteCollection(properties)))
        {
            SPWebCollection siteWebs = oSPsite.AllWebs;
            foreach (SPWeb web in siteWebs)
            {
                try
                {
                    SPList list = null;
                    try
                    {
                        list = web.Lists["Images"];
                    }
                    catch { }

                    if (list != null)
                    {

                        list.EnableModeration = isEnabled == false ? false: true;
                        list.Update();
                    }
                }
                finally
                {
                    if (web != null)
                        web.Dispose();
                }
            }
        }
