Try This

 private void pictureBox1_Click(object sender, EventArgs e)
        {
            this.Controls.Remove(pictureBox1);
        }

if delete on keyboard is selected the picture(has focus).

protected override bool ProcessCmdKey(ref Message msg, Keys keyData)
        {
            if (keyData == Keys.Delete)
            {
                if(pictureBox1.Focus())
                {
                    this.Controls.Remove(pictureBox1);
                }
                return true;
            }
            return base.ProcessCmdKey(ref msg, keyData);
        }

You can access the PictureBox from the controls and use the ControlCollection.Remove method.

Here is a sample code:

// Remove the PicturBox control if it exists.
private void deleteButton_Click(object sender, System.EventArgs e)
{
   if(panel1.Controls.Contains(pictureBox))
   {
      panel1.Controls.Remove(pictureBox);
   }
}

More documentation can be found here

EDIT:

Refer to this link on how to monitor KeyPress events in C#
