I have a MacBook Pro, and the Operating System is OSX, Version 10.6.8, which I think is up to date. I also have an IPhone 4, also with up to date software. I seem to be unable to transfer the photos I have taken on my IPhone to my computer. Preview lists no files when I try to transfer them, and my itunes sync seems to only sync scanned photos on my Macbook to my Iphone, and not the JPGs on my Iphone to my Macbook. I am really not a very techy person, so simple answers would be appreciated.
