Copying individual photos

In addition to copying albums or events, you can also drag individual photos from iPhoto Library Manager's photo browser and drop them on another library in your library list to copy the photos and their metadata over. No albums will be recreated when doing this, but the photos will be imported grouped into events with the same name as the events they belong to in the original library.

To ensure that this extra information will come over, you should drag the photos from iPhoto Library Manager’s image browser, and not from a Finder window or some other program that lets you drag files. If you drag from somewhere else, they will be treated as regular photos, and the extra information associated with them will not be brought into the destination library.
