I use dropbox to share my iTunes database (located on a Western Digital Sharespace NAS) between my Mac Mini and my wife’s MacBook. I tried it with iPhoto, but the performance was terrible. A colleague said that I could simply put the iPhoto library file on the NAS and run both as referenced libraries (where the files are not copied to the iPhoto folder when imported), since putting the file on the NAS was the same as putting it in the dropbox folder. I just couldn’t run iPhoto at the same time on each machine. I did that, opened iPhoto up separately on my Mac Mini, then on her macbook, and everything seemed fine. Now, I have a folder on my Mac Mini desktop labeled “1”, and it has 3006 .jpg files in it. Where did this folder come from? I don’t remember seeing it there before I removed my iPhoto library from the dropbox folder and put it onto the NAS.
