I'll assume that you need the image saved in the user profiles table.

You need to add this field to the user entity :

public byte[] Image { get;set; }

and set

user.Image = new byte[file.ContentLength];
file.InputStream.Read(user.Image,0, file.ContentLength);

Hope this helps.

Full Example here :

[HttpPost]
        public ActionResult Edit(UserProfile userprofile, HttpPostedFileBase file)
    {

        if (file != null && file.ContentLength > 0)
        {
            // extract only the fieldname
            var fileName = Path.GetFileName(file.FileName);
            // store the file inside ~/App_Data/uploads folder
            var path = Path.Combine(Server.MapPath("~/App_Data/uploads"), fileName);
            file.SaveAs(path);
        }

        if (ModelState.IsValid)
        {
            string username = User.Identity.Name;
            // Get the userprofile
            UserProfile user = db.userProfiles.FirstOrDefault(u => u.UserName.Equals(username));

            // Update fields
            user.Image = new byte[file.ContentLength];
            file.InputStream.Read(user.Image,0, file.ContentLength);

            user.FirstName = userprofile.FirstName;
            user.LastName = userprofile.LastName;
            user.Email = userprofile.Email;
            user.Motto = userprofile.Motto;

            user.PlaceOfBirth = userprofile.PlaceOfBirth;
            user.HowManyBikes = userprofile.HowManyBikes;
            user.BesideYourBeth = userprofile.BesideYourBeth;
            user.NicestRide = userprofile.NicestRide;
            user.WorstRide = userprofile.WorstRide;
            user.AmountKmPerYear = userprofile.AmountKmPerYear;
            user.AverageSpeed = userprofile.AverageSpeed;
            user.AbleToChatWhileRiding = userprofile.AbleToChatWhileRiding;
            user.PhoneNumber = userprofile.PhoneNumber;

            db.Entry(user).State = EntityState.Modified;

            db.SaveChanges();

            return RedirectToAction("Edit", "Account");
        }

        return View(userprofile);
    }
