Hi, first time poster, long-time user with a one-day-old iPad, here.
This might be a bit finicky of me, but would an option whereby the pictures in a slideshow are displayed oriented to the screen be possible? That is, so that the long axis of the picture is oriented to the long axis of the screen, whether the picture is portrait or landscape? Aesthetically, I just prefer to turn the screen sometimes without the picture twisting and resizing. End result is the same, so it's not a big thing. Just thought I'd mention it.
Keep up the good work!
