How to Merge Several Different iPhoto Libraries Together?

If you have photos scattered across several different machines in multiple iPhoto libraries, then you can merge them together. You can merge multiple iPhoto libraries together by using 'iPhoto Library Manager'. You can copy all your photos to the new Mac or access them directly from the individual machines. The 'iPhoto Library Manager' allows you to organize your photos among multiple iPhoto libraries. You can also browse your photos in all your libraries directly from the iPhoto Library Manager without having to open each library. When you transfer photos from one iPhoto library to another, then it will transfer them along with titles, descriptions, dates, keywords, ratings, faces and place information. The iPhoto Library Manager also allows you to split up a large library into multiple smaller libraries.
