many photos in iPhoto have turned into thumbnails. How do I get regular size back?
I have a Macbook Pro with retina display. It is one year old and I am using Yosemite OS X 10.10.5. Going through my photos I see that hundreds of my photos have become thumbnail prints. Don't know how that happened but I want my original size prints back. How do I get them normal size again?
