after an image is moved to a new location, how to delete the image at the old location?

[zxo102]

Hi everyone,
     As shown in the code below (modified based on the Image.py in
wxpython demo), an image is created at location 1:  (50,10) with
rotated angle 1.12.  Now, suppose I got another set of new data, I want
to move the image to location 2:  (166,400) with rotated angle 1.5.
case 1:
     if I use
     "wx.StaticBitmap(panel, -1, bmp2, (166, 400), (bmp2.GetWidth(),
bmp2.GetHeight()))",
     everything is fine but I don't know how to delete the image at
location 1.
case 2:
     If I use
     "kk.SetBitmap(bmp2)" (see the code below),
     the rotated image (angle 1.5) is put to location 1: (50,10)
instead of location 2: (166,400). Or I don't know how to move the image
to the new location (166,400).

anybody knows how to solve the above problem?  Thanks  a lot.
