Converting base 64 String to image

I am trying trying to take a base 64 String that I am acquiring from a server, and converting it into an image which I will have in my application itself.
The error I am getting is:

'Image' does not contain a definition for FromStream' error

This is what I am trying to do:

        JSONArray jsonArray = jsonResponse.GetJSONArray("OurprocessResult");
                    JSONObject jObject = (JSONObject)jsonArray.Get(0);

                    String imageString = jObject.GetString("Image");
                    byte[] byteImage = Convert.FromBase64String(imageString);
                    MemoryStream ms = new MemoryStream(byteImage);
                    Image image = Image.FromStream(ms);

From Online research, it would seem that there might be a naming overlap for Image. According to Visual Studio, my "using System.Drawing" is unused.

Here are my Usings:

using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
using Android.Telephony;
using Org.Json;
using Android.Media;
using System.IO;
using System.Drawing;

IS a name overlap the problem? If not, what is?
