After losing a lot of photos I keep multiple back ups of my photo library. My photos take up so much space on the internal hard disk I want to load iPhoto from my external HDD. The only way I see it is possible was to copy the iPhoto Icon that contains the "contents package" to the External HDD, Delete the icon on the internal drive and link the APP to my external HDD. Here's my problem. I already added all the photos to my external and removed them from my internal drive because I was at 95% HDD capacity. I don't want to transfer them back to my Internal drive and then transfer the contents package back to my external. There has to be another way, any ideas?
