i moved files around in the photos folder (consolidated all files and folders into one folder) because i am an idiot/virgo and like to 'clean' things
Unless you can return things to the way they were, you'll need to create and populate a new library.
To create and populate a new library:
Note this will give you a working library with the same film rolls and pictures as before, however, you will lose your albums, keywords, books, calendars etc.
Move the iPhoto Library Folder to the desktop
Launch iPhoto. It will ask if you wish to create a new Library. Say Yes.
Go into the iPhoto Library Folder on your desktop and find the Originals folder. From the Originals folder drag the individual rolls to the iPhoto Window and it will recreate them in the new library.
When you're sure all is well you can delete the iPhoto Library Folder on your desktop.
In the future, in addition to your usual back up routine, you might like to make a copy of the library6.iPhoto file whenever you have made changes to the library as protection against database corruption.
Remember: It is strongly advised that you do not move, change or in anyway alter things in the iPhoto Library Folder as this can cause the application to fail and even lead to data loss.
Just because a virgo doesn't understand the layout, doesn't mean it's untidy 😉
