Margin for splitting a list of images in flowLayoutPanel

Question

I use flowLayoutPanel as a collection of images that come from a list of images which can be clicked and afterwards displayed in bigger pictureBoxes. I wonder if there is any possibility to make a margin in that panel so for example if I want to save those images into one PDF file, I can choose to split a list of images into two lists. I thought about drag and drop or choose method but this one is much easier to use. Here is the code of displaying images from a list into smaller pictureBoxes in flowLayoutPanel :

foreach (Image image in images)
{
    PictureBox pf = new PictureBox();
    pf.SizeMode = PictureBoxSizeMode.StretchImage;
    pf.Height = 150;
    pf.Width = 170;
    pf.Image = image;
    pf.Click += new EventHandler(pictureClicked);
    flowLayoutPanel2.Controls.Add(pf);
}

And a click method :

public PictureBox clickedPicture; 

void pictureClicked(object sender, EventArgs e)
{
    if (clickedPicture != null)
        clickedPicture.BorderStyle = BorderStyle.None;
    clickedPicture = (PictureBox)sender;
    clickedPicture.BorderStyle = BorderStyle.FixedSingle;
    pictureBoxFront.Image = clickedPicture.Image;
}
