Some time ago, I moved a large iPhoto library, as my macbook's hard disk was getting full, onto an external drive. Since then I put a new, large, HD into my Mac. Also, in the meantime I have been importing photo's into a new library on this Mac; I essentially have two iPhoto libraries. I would like to export the smaller library, to say a pen drive, and then import these into the large library on the external drive before moving this back onto the Mac. Q: Is it possible to export the contents of an entire iPhoto library, and then do a mass import? please can someone help me?
