I have a picture on my iPhone home page (the picture that shows when you first turn on the phone). Honestly, I don't know I got that picture there because I don't have it saved in my mac nor can I find a copy of it in my iPhone's photos. So my question: how can I save that picture to my mac? I really like the picture but I would like to change the home page pic every once in awhile, however I'm afraid if I change it, I'll lose it forever. Can someone help me? TIA!
