I have an ibook and I have iphoto - can't imagine that you don't.
I'm a computer ditz - so it's a good thing that it popped up in my icon bar at the bottom of my screen when I first turned on the computer!
I didn't even have to look for it - BUT it took AlaskaYorkie to tell me how to use it - like I said, I know nothing about computers - that's why I have a mac, they are pretty self-explanatory - except for iphoto!
