Do I need to worry about duplicate file names?
Because of having several different point-and-shoot cameras that use the same filing naming prefix and also re-setting file numbering in my cameras I have ended up with different photos that have the exact same file names. E.g., Several different photos with the file name "DSCN0115". Is this a problem in iPhoto? I had some problems with thumbnails becoming mixed up in an early version of iPhoto (maybe 06).
