Your life is is one big photo opportunity — which explains why your photo library is getting bigger every day. Well, good news: iPhoto now supports up to 250,000 images. That means you can confidently shoot over a thousand photos per month for the next 20 years. (Better get cracking.) Navigating your larger library is a breeze now too. As you move the scroll bar, a new see-through Scroll Guide appears to show you what photos or rolls are currently displayed.
