Against my wife's wishes, I am transitioning her to a Mac, replacing her current Windows laptop with an iMac (I already have an MBP). Her computer stores our photo collection, thousands of pics of our two kids. What is the best way to manage a large photo library in OS X? Do I just store the photos in folders exactly like i do in Windows? If so, I guess I need to figure out how to download and remove the images from her phone to the folder. Or is keeping them in iPhoto the way to go? Or some other program?
