        MembershipUser user = Membership.GetUser();
      imCropped.ImageUrl = (File.Exists(Server.MapPath("..") + @"\Users\" + user.ProviderUserKey.ToString() + @"\" + user.ProviderUserKey.ToString() + ".gif"))? "~/Users/" + user.ProviderUserKey.ToString() + "/" + user.ProviderUserKey.ToString() + ".gif" : "~/Images/thumb.gif";
}

protected void ButtonJcrop_Click(object sender, EventArgs e)
    {

       ...

        String mapPath = @"\Users\" + user.ProviderUserKey.ToString() + @"\" + user.ProviderUserKey.ToString() + ".gif";
        bmpCropped.Save(Server.MapPath("..") + mapPath);
        imCropped.ImageUrl = Request.ApplicationPath + mapPath;
