Tengo un problema de falta de memoria cuando intento cargar algunas imágenes en un cuadro de imagen.

public void button2_Click(object sender, EventArgs e)
    {


        FolderBrowserDialog dialog = new FolderBrowserDialog();
        dialog.ShowDialog();
        string selected = dialog.SelectedPath;

        string[] imageFileList = Directory.GetFiles(selected);


        int iCtr = 0,zCtr = 0;
        foreach(string imageFile in imageFileList)
        {

            if (Image.FromFile(imageFile) != null)
            {
                Image.FromFile(imageFile).Dispose();
            }

            PictureBox eachPictureBox = new PictureBox();

            eachPictureBox.Size = new Size(100,100);
           // if (iCtr % 8 == 0)
            //{
             //   zCtr++;
              //  iCtr = 0;
            //}
            eachPictureBox.Location = new Point(iCtr * 100 + 1, 1);
            eachPictureBox.Image = Image.FromFile(imageFile);
            iCtr++;

            panel1.Controls.Add(eachPictureBox);

        }


    }`enter code here`
