I'm sure this was discussed a decade ago but we are behind the times. LOL! All kidding aside, we have an old iMac, circa 2004. I have updated it to OS X but it can no longer update the OS and still has iPhoto. Everything I've read says to update the OS so iPhoto will convert photos into the new Photos app, which I cannot do. My iPhotos library says there are about 10,000 photos (many duplicates) stored in there so what is the best way to get them out? I want to burn them onto CDs or store on thumb drives. Do I need to export one by one or batch export? If so, will that keep the initial quality intact?
