draw rectangle over top of background image on panel with pen

so, can I go from the lockpixel into a new method to open and draw that image in a panel with a buttonclick method?
like, how do i get to see the image with the rectangle drawn on it from this point?

hey! how's this Sergey

public Form1()
{
InitializeComponent();
}
private void LockUnlockBitsExample(PaintEventArgs e)
{

Bitmap myImage = new Bitmap("C:\\Users\\jason\\Documents\\IProject\\code\\imageAlign\\imageAlign\\bin\\Debug\\good.jpg");


// Lock the bitmap's bits.
Rectangle rect = new Rectangle(0, 0, myImage.Height, myImage.Width);
System.Drawing.Imaging.BitmapData bmpData =
myImage.LockBits(rect, System.Drawing.Imaging.ImageLockMode.ReadWrite,
myImage.PixelFormat);

// Get the address of the first line.
IntPtr ptr = bmpData.Scan0;

// Declare an array to hold the bytes of the bitmap.
int bytes = Math.Abs(bmpData.Stride) * myImage.Height;
byte[] rgbValues = new byte[bytes];

// Copy the RGB values into the array.
System.Runtime.InteropServices.Marshal.Copy(ptr, rgbValues, 0, bytes);


// Set every third value to 255. A 24bpp bitmap will look red.
for (int counter = 2; counter < rgbValues.Length; counter += 3)
rgbValues[counter] = 255;


// Copy the RGB values back to the bitmap
System.Runtime.InteropServices.Marshal.Copy(rgbValues, 0, ptr, bytes);

// Unlock the bits.
myImage.UnlockBits(bmpData);

// Draw the modified image.
e.Graphics.DrawImage(myImage, 0, 150);
}

private void button1_Click(object sender, EventArgs e)
{
openFileDialog1.Filter = "JPEG IMAGES|*.jpg";
openFileDialog1.InitialDirectory = "C:\\Users\\jason\\Documents\\IProject\\code\\imageAlign\\imageAlign\\bin\\Debug";
openFileDialog1.Title = "Open Image";
if (openFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
panel1.BackgroundImage = Image.FromFile(openFileDialog1.FileName);
panel1.Invalidate();
}
Bitmap myImage;
myImage = (Bitmap)Image.FromFile(openFileDialog1.FileName);
panel1.BackgroundImage = myImage;

// Array for keeping the sums of each row of pixels
float[] resultArray = new float[myImage.Height];

// Populate the array with data from each row of pixels, using the brightness value
for (int i = 0; i < myImage.Height; i++)
{
float value = 0;
for (int j = 0; j < myImage.Width; j++)
{
value += myImage.GetPixel(j, i).GetBrightness();//get colour of pixel and that Hue-Saturation-Brightness values
}
resultArray[i] = value;
}
}

I ran it - it ran ok and loaded the image. but are the lockpicks and image display linked. they seem separate and unrelated. So, I run the lockpicks ok, but then run the buttonclick as a separate thing.

"better move it to the question where you can format it"

it was in the 'Have a Question or Comment'link. Is that wrong?
