i don't use it. i don't like how it organizes my photos and most of my pictures look like crap on my macbook, unless they are 4+ megapixels. i got used to just using windows explorer to organize all my photos and i hardly do any editing. according to this article it uses up a little chunk of space i'm wondering if i delete it, will it cause any trouble? i believe preview will still function, thats all i need. how would i go about deleting it? also, if i wanted it back, how would i do that?
