Hi, I have 2 main problems; 1 All the family photos are stored in iphoto in my log on name but do not appear in my wife's user account when she logs on. How do I either copy or preferably allow access to my iphoto to my wife when she is logged on? 2 I lost/deleted some photos and replaced them from an external storage system. In general they are OK but some show a thumbnail of the photo but when I click into it to view full screen or edit the photo is replaced with a black exclamation mark within a white circle on a black screen. How can I view/edit these photos? Any help would be most appreciated.
