So it's all really quite simple in the end! Happy I checked things. I now also get the "random" element; I believe The Gimp doesn't set a alpha layer unless creating the image involved a layer with transparency; that would give exactly the results I saw. The "magical" trick of converting a bmp to png using Python must mean that that Python library saves a alpha channel anyway. Phew, at least we got there in the end. Thanks again, Kas.
