I would simply remove PictureBox from it's parent using Control.Remove. It should follow the lazy pattern.

C#

class MyForm : Form {

    internal PictureBox {
        get {
            if (fMyPictureBox == null) {
                fMyPictureBox = new PictureBox;
                //whatever you need to set up it
                pictureParent.Controls.Add(fMyPictureBox);
            }
            return fMyPictureBox;
        }
    } //PictureBox set

    internal void ResetPicture() {
        pictureParent.Controls.Remove(fMyPictureBox);
        fMyPictureBox = null; //later will be re-created when needed
    } //ResetPicture

    //...

    PictureBox fmyPictireBox;
    Panel pictureParent;
} //class MyForm

Besides, in most cases PictureBox is not needed at all.
If you're manipulating the image, chances are, you don't need it in your case.
Consider the alternative:
