Hi, today I was looking for 1-2 GB of space that "disappeared" from my hard disk after synchronizing part of my iPhoto '09 library with my iPhone... I've found (I think) that it saved a copy of the foto in the iPod Photo Cache folder within the iPhoto library, so I've solved the mystery... but then, I've noticed also a 1.18 GB folder named Modified within the iPhoto library.... I'm sure I've not modified more than 20-30 photos within iPhoto (I've rotated some images) and changed the location or date settings of 2-3 events, but there are about 800 photos within the Modified forlder... what is iPhoto doing? Does it like to duplicate photos even if it is not necessary...? Is there a way to avoid the duplication (can I tell it to modify originals instead of duplicating them?) or at least a way to consolidate the changes by moving the modified versions of the photos onto the original ones? Thank you in advance for any help!
