I occasionally export entire groups of photos from iPhoto to my hard drive where I keep them in folders. I don't want them on iPhoto because they are private so I don't want people seeing them when I'm showing them stuff from iPhoto. Today I noticed iPhoto is automatically scanning my hard drive and importing those folders back into iPhoto as events. This is crazy. I'm going through and deleting images from iPhoto, wondering if they are actually also deleting from my hard drive. I've never noticed this before. I can't find a setting for this. Anyone who can help?
