Problem: I have created a Smart Album in iPhoto with only one criteria (Filename contains _1). The result is that only one photo appears in the Smart Album.

When I look in my library at the filenames of photos I know that I have HUNDREDS. Spotlight confirms this and they are located in my iPhoto Library folder.

I assume that there is something wrong with the index that iPhoto is using.

How do I fix this?

BTW: The purpose of this smart album is to delete duplicates in my iPhoto Library.

Computer Stats:
1.67 Ghz PowerBook G4 running OS X 10.4.2.
iPhoto version 5.0.4

Thanks in advance!
