Maybe this is what you are looking for:

public class Activity1 : Activity
{
    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);

        this.SetContentView(Resource.Layout.layout1);

        WebClient web = new WebClient();
        web.DownloadDataCompleted += new DownloadDataCompletedEventHandler(web_DownloadDataCompleted);
        web.DownloadDataAsync(new Uri(@"http://your.image.com"));
    }

    void web_DownloadDataCompleted(object sender, DownloadDataCompletedEventArgs e)
    {
        Bitmap bm = BitmapFactory.DecodeByteArray(e.Result, 0, e.Result.Length);
        FindViewById<ImageView>(Resource.Layout.layout1).SetImageBitmap(bm);
    }
}

I haven't tested this one, but I think it should do the job :)
