c# - Upload Images while creating new Model

I'm going to create profile for my users in ASP.Net MVC application. Users creation controller is something like this:

[HttpPost]
[ValidateAntiForgeryToken]
public ActionResult Create(UserProfileViewModel userViewModel)
{
    if (ModelState.IsValid)
    {
        ....
    }

    return View(userViewModel);
}

Besides, each user model got several properties including one photo. Everything goes well till I want to add an input field to accept photo.

@Html.TextBoxFor(model => model.ImageUrl, new { type = "file" })

And I add below field to UserProfileViewModel:

[Display(Name = "Profile Photo")]
public HttpPostedFileBase ImageUrl { get; set; }

Among snippets to upload a photo and answers to my previous question, it seems uploading photo was considered as a separate task. i.e. I need an individual form and controller to upload a photo (like first part of this answer).

I want to know are there any methods that I can create whole user profile in one form and pass its photo to the same controller (which included photo in UserProfileViewModel)?

I need to note I don't know to use jQuery or AJAX and I want to use standard HTML helpers for this task.

Update: My View Looks like this:

@model ProjectManager.Models.UserProfileViewModel 

@{
    ViewBag.Title = "Create";
}

<h2>@ViewBag.Title</h2>


@using (Html.BeginForm()) 
{
    @Html.AntiForgeryToken()

    <div class="form-horizontal">
        <h4>User Profile</h4>
        <hr />
        @Html.ValidationSummary(true)

        <div class="form-group">
            @Html.LabelFor(model => model.Description, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Description)
                @Html.ValidationMessageFor(model => model.Description)
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.Name, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Name)
                @Html.ValidationMessageFor(model => model.Name)
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.Age, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.EditorFor(model => model.Age)
                @Html.ValidationMessageFor(model => model.Age)
            </div>
        </div>

        <div class="form-group">
            @Html.LabelFor(model => model.ImageUrl, new { @class = "control-label col-md-2" })
            <div class="col-md-10">
                @Html.TextBoxFor(model => model.ImageUrl, new { type = "file" })
                @Html.ValidationMessageFor(model => model.ImageUrl)
            </div>
        </div>

        <div class="form-group">
            <div class="col-md-offset-2 col-md-10">
                <input type="submit" value="???" class="btn btn-default" />
            </div>
        </div>
    </div>
}

<div class="rtl text-right">
    @Html.ActionLink("Back To List", "Index")
</div>

@section Scripts {
    @Scripts.Render("~/bundles/jqueryval")
}

File inputs are not sent in the request unless your form element contains the enctype = "multipart/form-data" attribute. Change the view code to

@using (Html.BeginForm("Create", "User", FormMethod.Post, new { enctype = "multipart/form-data" }))
{
    ....
}
