Add image and value to a panel?

I was able to add image to my panel with the following code, but now my problem is i need to retrieve some information from the image etc(key value)

Is that possible to add in a value to every image ?so I can get it when I need

                foreach (System.Drawing.Image img in imagelist)
            {
                PictureBox imagePicBox = new PictureBox();
                imagePicBox.Name = "image" + imagePanel.Controls.Count.ToString();


                    imagePicBox.Image = img;




                imagePicBox.Size = imagePicBox.Image.Size;
                imagePicBox.BackColor = Color.Black;
                imagePicBox.SizeMode = PictureBoxSizeMode.StretchImage;
                imagePicBox.BorderStyle = BorderStyle.FixedSingle;


                imagePanel.Controls.Add(imagePicBox);
