Hi,

Why you load the image in the paint event?
 You just load it once and that's all, after that all you would have to do
is reposition your picturebox.

below you will find a piece of code I just did for testing,
When I click on the button I load an image, the picturebox has SizeMode set
to autosize
the picturebox is inside the panel
   //
   // panel1
   //
   this.panel1.Controls.Add(this.pictureBox1);

This is what I do when the button is pressed, you have to change it to
refrect your need
  private void button1_Click(object sender, System.EventArgs e)
  {
   Bitmap b = new Bitmap( @"c:\imagenlogin.jpg" );
   pictureBox1.Image = b;
  }

I added a scrollbar next to the panel, this is the code for the handler
  private void vScrollBar1_Scroll(object sender,
System.Windows.Forms.ScrollEventArgs e)
  {
   pictureBox1.Top = -e.NewValue;
  }

It does work as intended, if you still need help let me know and I will post
the complete code for the page

Cheers,
