''You can use the Windows API and some masking to
''accomplish this requires some planning ahead,
''such as making a mask file with the white background
''you mention (and making it black in the image
''you want to "overlay" on the screen)

''Examples of how I've done this in a program of mine
''are below:

' Declare the Windows API function (for details see AllAPI.net)

Public Declare Function BitBlt _
  Lib "gdi32" (ByVal hDestDC As Long, _
               ByVal xDest As Long, ByVal yDest As Long, _
               ByVal nWidth As Long, ByVal nHeight As Long, _
               ByVal hSrcDC As Long, _
               ByVal xSrc As Long, ByVal ySrc As Long, _
               ByVal dwRop As Long) As Long

Public Function dBlankOut()
' This "blanks out" where the new image will overwrite the old (masking)
    dBlankOut = BitBlt(frmResources.picWork.hDC, _
                frmResources.picWork.ScaleWidth - Mask.ScaleWidth, 0, _
                Mask.ScaleWidth, Mask.ScaleHeight, _
                Mask.hDC, 0, 0, vbSrcAnd)
End Function

Public Function dPutImage()
' This puts the new image in the black area created by the masking
    dPutImage = BitBlt(frmResources.picWork.hDC, _
                frmResources.picWork.ScaleWidth - Overlay.ScaleWidth, 0, _
                Overlay.ScaleWidth, Overlay.ScaleHeight, _
                Overlay.hDC, 0, 0, vbSrcPaint)
