Thanks for the quick response.

I intend to import my iphone's camera roll to my iPad's camera roll folder in a natural chronological order, so that's basically with the newest at the bottom.

I managed to transfer photos in the old to new order (newest at the bottom) only by selecting individual photo, but if I mass select with the select all function, it will go in reversed order.

Is there an option where I can mass select and still get the old to new order? I actually used a similar app called "photosync", they have an option to select all photos in both ways (new to old/old to new), unfortunately the app crashes every 20-30 photo. It would be great if Photo Transfer App has a similar way to sort out the photo order.
