Hi umirabelle, nice to hear from you here, but as you are replying to a thread well over two years old, it's doubtful whether those posters will return for a further discussion.It may erase your original files in iPad if you sync iPad with Mac iTunes. So I suggest you to download a trial version of Photo Transfer to help you. With the apps, all your original files will be kept better and can be directly transfer from Mac to iPad.
