I used to have a 16 GB iPhone and each time I started running out of space I transferred the pics to my Mac and then deleted them from my iPhone. Now that I have plenty of space on my iPhone 6 (64GB) I'd like to transfer those old pics on my new iPhone. 1. Will those pics remain intact, or will iTunes mess them up in any way (resize or whatnot)? 2. Will they blend nicely with my current Camera Roll (i.e. date-wise etc)? Thanks.
