OK, I am pretty new to Macs....just got my iMac G5 less than a week ago. I had some pictures of my camping trip on a CD. I copied them to the Mac, in a folder named "Muskegon" in my "Pictures" directory. I was surprised to see the pictures were not in iPhoto when I opened it, so I dragged the "Muskegon" folder to iPhoto, and there is now a "Muskegon" folder in iPhoto containing all the pics. Great. But... I noticed that it did not simply link my photos to iPhoto, it copied them to iPhoto's directory, and made another directory containing thumbnails of the photos. So now, I have 2 copies of the exact same pictures in different locations, and another bunch of thumbnails. Doesn't it seem kind of wastefull to have multiple copies of the exact same file, in different locations? What I don't understand is why doesn't iPhoto leave the pics in their original locations, and just allow them to be browsed and edited by iPhoto without duplicating them? And also, why does iPhoto create additional images for thumbnails - can't it just use a thumbnail "preview" of the original image without creating more files? Pictures are not big in filesize, but if you have many many pictures, having duplicates of the same exact file just seems redundant and space-wasting. I could, of course, delete the "Muskegon" folder I have in the Pictures directory of my home folder, but then I would have to browse through iPhoto's directories (which are labeled by date, and not name) to find pics if I wanted to open them in photoshop or something, which would make it very difficult to find photos, and way more difficult than it should be. I know I must be missing something here, because this is definitely not sensible for a program to be doing - what am I doing wrong? Can iPhoto be set to organize its directories by name instead of date, or anything?
