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);
}
}

events in C#
