iPhoto newbie question, I have 65Gbs of pictures & videos from the past 3 years, and yesterday was the day that I imported them all into iPhoto. I noticed that when importing them, that they actually get copied into iPhoto. So that would be 130Gbs altogether, taking a big part of my hard drive space. And I really don't wish to have my mac to run slower. Does iPhoto always have to make a copy of the originals into its library?
