        // Define upload path
           $destinationPath = public_path('/profile_images/'); // upload path
        // Upload Orginal Image           
           $profileImage = date('YmdHis') . "." . $files->getClientOriginalExtension();
           $files->move($destinationPath, $profileImage);

           $insert['image'] = "$profileImage";
        // Save In Database
            $imagemodel= new Photo();
            $imagemodel->photo_name="$profileImage";
            $imagemodel->save();
        }
