Photoshop Elements 9 - Mac OS - iPhoto to Photo

Hello everyone.

I stoped use Photoshop Elements 9 since some years.

I would like to reused it but I notice that this version is link to iPhoto (pictures software with the macOS before Yosemite version). After Yosemite the macOS used a new software "Photo", unknown by Photoshop Elements 9.

How I can upload the picture in Photo library to PE Organizer 9 ?

Thank you in advance for your help
