Saving pictures

[dr3amxstar]

Hi im using VB 2005. I did some drawing on a bmp and assign it to a picturebox whereby after i save the picturebox. However the save picture is very small whereas the picture i see on the form is quite big. Why is this so?

 'Make the PictureBox control large enough to fit all your drawings.       
        Me.PictureBox1.Size = New Size(5000, 5000)
        'Make a bitmap object with the size of the PictureBox control.       
        Dim bm As New Bitmap(Me.PictureBox1.Size.Width, Me.PictureBox1.Size.Height)
        'Create graphics form the bitmap object        
        Dim g As Graphics = Graphics.FromImage(bm)
        'Draw whatever you want in bitmap
 Me.PictureBox1.Image = bm
        'PictureBox1.Image.Save("G:\Sequence1.bmp")
