I have a large number of photos within iPhoto 11 and I want to backup and reduce the size of my local iPhoto library to free up disk space on my laptop.
One scenario I've tried is:
- Show iPhoto package contents and open the Masters folder
- Copy say 2011, 2012 folder tree to an external formatted USB drive
- Delete the 2011 and 2012 trees
- Open iPhoto, holding the Command + Option Keys and selecting 'rebuild database'
This moves the original images from iPhoto, but leaves the thumbnails and events, which I'm assuming is stored in some other local database.
How do I reset the iPhoto system so it now only sees and displays the 2013. In other words how to get iPhoto to forget about the older images ?
