asp.net display image from byte array

Question

I have a byte array and trying to display image from that.

using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Data.Linq;

namespace RealPortableTerminal
{
public partial class resim : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {
        PortableTerminalDbEntities entity = new PortableTerminalDbEntities();
        byte[] arr = (from b in entity.Sicil where b.Id == 31 select b.Fotograf).First();

        Image rImage = null;
        using (MemoryStream ms = new MemoryStream(arr))
        {
            rImage = Image.FromStream(ms);
        }
    }
}
}

It underlines FromStream and says 'System.Web.UI.WebControls.Image' does not contain a definition for 'FromStream'. It seems adding System.Data.Linq reference did not changed anything. Am I missing something ? Btw I am pretty sure I take byte array from database correctly.

<img id="img" runat="server" alt=""/>

In code behind

string base64String = Convert.ToBase64String(arr, 0, arr.Length);
img.Src = "data:image/jpg;base64," + base64String;

You wouldn't need MemoryStream.
