Paint on a Bitmap instead of directly painting on the picturebox. In the
picbox' paint event draw the bitmap on the picturebox. The Bitmap can be
save to a JPG:

bmp.Save("myfile.jpg", Imaging.ImageFormat.Jpeg)

Draw the image onto a bitmap instead. Create a new 'Bitmap' object with
the preferred size ('Dim b As New Bitmap(...)'), then obtain a
'Graphics' handle ('Graphics.FromImage') and draw onto the bitmap. Then
you can draw the bitmap to the picturebox in its 'Paint' event handler.
You can save the image by calling 'b''s 'Save' method. Don't forget to
call the 'Graphics'' object's 'Dispose' method after you finish using it.
