How to delete the originals of edited photos on iPhoto 11?
CleanMyMac 2

CleanMyMac 2 has an iPhoto Cleanup feature. It will scan your library and give you the ability to delete photos that have been cropped, resized, rotated, or otherwise edited.

By default, it will delete the photos that have been rotated and/or with fixed Red-Eye, however you can also choose to delete the originals of any photos that have been edited in any way.



I have used this multiple times, and it's worked great, although it's worth noting that in the Rebuilding Library stage, it might appear that it's crashed, but it's still going - it does take a very long time!
