I got my macbook couple weeks ago, and so far it's been great. However, there's one problem: i like to collect icons/dps (i know, it's weird), and before on my windows laptop, i just put them into a folder and select the "picture" option for the folder. That way every time i open the folder, i can see all my icons displayed. But on my mb, there doesn't seem to be that option and all my icons only displays the standard preview icon thing . Does anyone know how to change the folder options? Secondly, whenever i import pictures from another folder on my computer to iPhoto, does it duplicate the photo or just use the copy that already exists on the computer? I don't want the same picture to exist twice and take up twice the space.
