Please help.

Answer 1

I've had a stubborn image too, that wouldn't go away by setting the Image and InitialImage to null. To remove the image from the pictureBox for good, I had to use the code below, by calling Application.DoEvents() repeatedly:

            Application.DoEvents();
            if (_pictureBox.Image != null)
                _pictureBox.Image.Dispose();
            _pictureBox.Image = null;
            Application.DoEvents();
            if (_pictureBox.InitialImage != null)
                _pictureBox.InitialImage.Dispose();
            _pictureBox.InitialImage = null;
            _pictureBox.Update();
            Application.DoEvents();
            _pictureBox.Refresh();

Its so simple! You can go with your button click event, I used it with a button property Name: "btnClearImage"

// Note 1a:
// after clearing the picture box 
// you can also disable clear button 
// by inserting follwoing one line of code:

btnClearImage.Enabled = false   

// Note 1b:
// you should set your button Enabled property
// to "False"
// after that you will need to Insert 
// the following line to concerned event or button
// that load your image into picturebox1 
// code line is as follows:

btnClearImage.Enabled = true;
