        public byte[] Picture2 { get; set; }

        public byte[] Picture3 { get; set; }

// GET:/ Accommodation/Edit/5

public ActionResult Edit(string id)

        Accommodation accommodation = db.Accommodation.Find(id);
        ViewBag.SelectedAustraliaStateId = new SelectList(db.AustraliaStates, "AustraliaStateId", "AustraliaStateName", accommodation.SelectedAustraliaStateId);

        return View(accommodation);
    }

// POST:/ Accommodation/Edit/5

[HttpPost]
public ActionResult Edit(Accommodation accommodation)
{
    if (ModelState.IsValid)
    {
        db.Entry(accommodation).State = EntityState.Modified;

        //the following line is for re-assigning …
