So I have moved all of my photos from my pc over to my mac harddrive. When I look for the pictures in Finder it uses Preview to open the pictures. To see them in iPhoto I guess I have to import all of the pictures? Is that correct? If I do this the pics will be on my machine twice? Now let's say I have new pics on a camera that i'm trying to get on my machine. Is the only way to import into iPhoto or is there a way I can get the pics into my pre-existing folders? Does this make sense?
