I was pretty sure I did exactly what you described and just to be sure I just tried to insert a picture following
exactly the steps you described. Still nothing!
When I drag and drop the picture I don't see the picture in frame or the main BD page, although the src file name is populated with "pRnd_0858090160.jpg" (which isn't what it's actually called but I assume this is some kind of alias?). I then do exactly what you said (align middle and click insert) and nothing happens. I have now tried this a number of times with no joy and am really frustrated!
