Hello y'all. Just recently purchased a new iMac. I finished loading all of my old photos into iPhoto, about 4300 in all. While I was searching my hard drive (not sure what you call it, but on Windows was "My Computer"), I noticed a search folder called "All images". I noticed that it had about 9000 images in it, which is double what I had originally loaded. I noticed that each image is listed twice. A file could be called Pic 123.JPG, and there is the same pic only called Pic 123.jpg. Notice the lower and uppercase .jpg. While do I have all of these duplicate photos? Thanks. I dont ant all of my pictures to take up more hard drive space than necessary.
