I'm in the process of organizing thousands of photos in iPhoto (any tips are appreciated), and I have a few questions. I had it originally set to copy my files to the iPhoto library, but I want them to stay in my original file structure. I disabled that feature, but I'm not sure if my files are already stored in the iPhoto library. How can I check? If they are stored there and I delete them, what will happen to my keywords, faces, places, etc? I guess this brings me to my next question. I edited a few photos using iPhoto, and I noticed that the changes did not reflect on the actual image file. Are these changes being stored some where else? How can I make it overwrite my images? Thanks in advance!
