Graham, the passthrough feature isn't implemented yet in the official firmware. QGC detects that and grays out the option. Sorry for the confusion.
Ivo, yea, there's no way to save the image to the AQ. Only useful when loading a file from disk, really. I can't think of a clever way to pull that back up... that isn't too complicated to be practical, anyway. But I'll keep thinking on it.
Oh the date thing is totally screwed up over here! I grew up writing it the way you do, then moved here and had to relearn... to this day (30+ yrs) I have to think about the order every time I write a date. In fact I usually use 28-Apr-13 or something like that, just to make sure I'm not messing it up.
Cheers,
