I have built up my photo library in iPhoto with the setting 'copy items into photo library' ticked, which has made it necessary to delete the originals (to avoid effectively having two copies of every photo on the machine). Unfortunately, this makes it awkward to view the photos anywhere else (in Finder would be most useful), the only way to look at them in their traditional hierarchical folder layout outside iPhoto is right clicking on my photo library file in finder and selecting 'show package contents'. Because of this i'm trying to transition back to a system where i would have all the photos in their original folders and iPhoto would use them from there (without copying them all into the photo library file), as it would be nice to be able to view my photos without having to use iPhoto every time. Is there an easy way of doing this without losing all the events and albums that have been created, or will i effectively have to build the library from scratch again?
