Do photos saved on iPhoto use up computer memory?
Do the photos I have saved in iPhoto and MyPhotoStream use up the memory on my macbook or are they all just saved online? I'm wondering because I want to delete photos on my other iOS devices after syncing all of them onto just my macbook. But I won't do this if placing all my photos on my macbook will use up computer memory.
