I've imported photos in the iPhoto library. In iPhoto's preferences i have UNchecked the option "Copy items to the iPhoto Library". Still, i think photos are being copied nonetheless, because the iPhoto library file was many GB's large afterwards. On the other hand... when i do a "show file" in iPhoto of a specific photo, he opens the original location/folder and points to the original file ?! ==> so this leaves me very confused to say the least. Anyone knows what's going on?
