mac newbie. Here's what I am used to in Windows. 1. open a folder with pictures in it 2. double click any picture 3. now I see that picture and can hit the right or left arrows and it automatically shows the next/previous picture. Before I changed the default image program to iPhoto, if I double clicked an image, Preview would open it. Fine, but I had to x out and double click another image to see the next one. What happens when I "import" photos to iPhoto? I mean, EXACTLY what takes place? i.e. where does the original file go? where is my imported file? how does this work in terms of backups such as sugar sync? Maybe I'm asking for cake and to eat it too but what I would love is to be able to store pictures on my mac, look at them any time easily, and have them automatically backed up so that if anything happened to my machine, I could get the pics again. Thanks!
