Retrieve image path in mvc3 outside of my project folder/wwwroot folder

Question

Hi I'm stuck for an hour to fix the image retrieving from "D:\Sample" path. I'm retrieving the correct path but not displaying because of localhost:port "(mylocalhosthere):(port)/D:/Sample/sample1.jpg" . How can I display the image outside of my project path? Anyone help me. Thank you. Here's my code:

Controller:

public class UploadController : Controller
{
    //
    // GET: /Upload/

    public ActionResult Index()
    {
        const string root = @"D:\Sample";

        var all = Directory.GetFiles(root).Select(Path.GetFullPath).ToArray();

        return View(all);
    }

}

}

View:

@{
    ViewBag.Title = "Index";
}
@model string[]

@foreach(var image in Model)
{
    var aaa = System.IO.Path.GetFileNameWithoutExtension(image);
    <img src="@Url.Content(image)" alt='@aaa'/>
    <input type="checkbox" id= '@aaa' />
}
