Linking Edited and Original Files
Some background: I have been trying to restore my iPhoto (9.2.3) library after a crash appeared to corrupt the database. After unsuccessfully trying repairing and rebuilding the database in iPhoto, I followed the advice in the forums and used IPhoto Library Manager to rebuild the library from backup. This seems to have worked; all the files are there. But the rebuilding process created many duplicates (judging from the photo counts). Some older photos appear to be exact duplicates. Some are multiple jpgs associated with movie files or raw files (apparently generated by iPhoto). Some appear to have been scavenged from the trash (even some I thought were deleted years ago). Others appear to be duplicates of any vertical images (although both are vertical). All of these files I figure I can safely delete.
But--some of the duplicates represent edited images, which I obviously want to keep. But is there a way to manually recreate the link between the original and edited versions (like iPhoto generally does)? Barring that, is there a way to batch copy metadata from one photo to another? In all cases, it seems as though the original file has the better metadata (rating, lens info, keywords, original capture date as opposed to date modified) and it would be helpful to have that attached to the edited (i.e, current) version of the photo. Thanks for any advice.
