I opened up my iPhoto today and realized that the last 1.5 years of pics are gone. I have no idea what has happened. My 3 year old twins occasionally will get a hold of my laptop and press tons of buttons, but I really don't think they are at fault here. Is there anything I should do to find them? I will make an appt at our Apple Store on Sunday, but I was really hoping to recover them on my own. Has anyone else experienced this? I am running Leopard. Thanks!
