Anne, The photo's are all stored in the Library. What you moved was the "Albums" I-photo's file system is a little complicated. What I have done is mad a folder (On a separate drive) called "archive". I then export to that folder, (And make sure they are there and open OK). Then delete from the library. The downfall is you have to remember that those photo's are there. I do think there is a way I-photo stores a thumbnail so you still can view. I just have not taken the time to READ THE MANUEL like everyone else : ). Hope this helps, Frank
