Hey, thanks for implementing this! I modified your code to read as follows:

                             bmp =  
oldNotebook.GetImageList().GetIcon(imageindex)
                             newImageList = newNotebook.GetImageList()

                             if not newImageList:
                                 xbmp, ybmp = bmp.GetWidth(),  
bmp.GetHeight()
                                 newImageList = wx.ImageList(xbmp, ybmp)
                                 imageindex = 0
                             else:
                                 imageindex = newImageList.GetImageCount()

                             newImageList.AddIcon(bmp)
                             newNotebook.SetImageList(newImageList)

and this seems to keep the transparent parts. I don't know if it's the  
method of choice though.
