Hi, I have an iPhoto library on an external hard drive (I cannot remember how I copied it over there) that I can wirelessly connect to on my home network. I have added thousands of pictures to the iPhoto library on my MacBook and would like to copy those events and pictures to the library on my hard drive. Any ideas? My husband and I should just use time machine, but we filled up our hard drive before realizing that in order to set up time machine, it has to wipe the hard drive, so that's not really an option. TIA.
