c# - Drag-and-Drop an Image

Question

I have a form with 6 labels 4 of them have png Images in them. I have it set up so the user can drag one of the 4 images into label5 and label6 would give them a message to tell them which of the 4 they picked I have the drag drop part working but cannot figure out what code I need to tell them which was picked.

using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.IO;

namespace Drag_Drop_Tester2
{
public partial class Form1 : Form
{
    Image img1 = Image.FromFile("Peg_Red.png");
    Image img2 = Image.FromFile("Peg_Blue.png");
    Image img3 = Image.FromFile("Peg_Green.png");
    Image img4 = Image.FromFile("Peg_Orange.png");

    public Form1()
    {
        InitializeComponent();
    }

    private void DD_MouseDown(object sender, MouseEventArgs e)
    {
        Label lblPic = (Label)sender;
        lblPic.DoDragDrop(lblPic.Image, DragDropEffects.Copy);
    }

    private void DD_DragEnter(object sender, DragEventArgs e)
    {
        if (e.Data.GetDataPresent(typeof(Bitmap)))
            e.Effect = DragDropEffects.Copy;
        else
            e.Effect = DragDropEffects.None;
    }

    private void DD_DragDrop(object sender, DragEventArgs e)
    {
        Label lblPic = (Label)sender;
        Graphics g = lblPic.CreateGraphics();
        g.DrawImage((Image)e.Data.GetData(typeof(Bitmap)), new Point(0, 0));

        if ("code that goes here")
            lblMsg.Text = "You picked red";
        else
            lblMsg.Text = "I can't decide what you picked";
    }
}
}

Never mind I figured it out:

If (sender == label1)

lblMsg.Text = "You Picked Red";

I was making it harder then it needed to be
