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

    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.
