How to pass Image by Image to add to the database?

Question

I’m trying to add image to the database, how do I temporarily add object by object up, varying the object according to which index you upload? as I tried to do on line 7

I know there are inconsistencies in the code below, I’m trying to see how to add the images one by one, and then try to solve the rest

I still haven’t fixed all the code the relevant part of line 4 through 9

Controller

       [HttpPost]
    [ValidateAntiForgeryToken]
    public ActionResult Create([Bind(Include = "ImagemId,Image,ImagemTipo")]Imagem imagem,List <HttpPostedFileBase> upload)
    {
        List<Imagem> todasImagens;
        int contado = upload.Count;
        for (int x = 0; x < upload.Count;) {
         //parte que eu nao sei como fazer 
         HttpPostedFileBase up = uploa;


        }
        if(upload != null && upload.Count> 0) {
            var arqImagem = new Imagem
            {
                ImagemTipo = upload.ContentType
            };
            using (var reader = new BinaryReader(upload.InputStream))
            {
                arqImagem.Imagem = reader.ReadBytes(upload.ContentLength);
            }
            imagem.Imagem = arqImagem.Imagem;
            imagem.ImagemTipo = arqImagem.ImagemTipo;
        }

             db.Imagens.Add(imagem);
            db.SaveChanges();
        return View(imagem);
    }
