I can help you with this. The best way is to copy the libraries to a backup location first.
next you will want to choose one library as the master, to make things easier it should be the library with the most pictures
Then export the pictures from the other libraries into one folder,
after all the other libraries pictures have been export, click and drag them into iphoto when your master library is open
then the pictures will be imported.
after that they will need some clean up
then all the pictures will be in one library, you should then make a copy of that library on to another device.
Hi Kyle, thanks for getting back to me. Should I export the photos as ...."original, current, JPEG, TIFF or PNG"
