I cannot import photos into iMovie 10.1.6 in corrrect order
I am trying to make a slide show using iMovie 10.1.6 on my iMac running El Capitan10.11.6. I imported about 200 pictures into iMovie and they showed in the events window in the correct order. I decided I wanted to make changes to the order of the photos in the folder so I deleted the event as well as the project and started over. Now when I import the photos into iMovie the order of the photos is scrambled. I have tried everything I can think of to get the program to import in the correct order. I renamed the photos (1-200), dates and time do not seem to make any difference. I even tried to import the folder of photos into Photo and then import to iMovie but it scrambles the photos in Photo as well. I tried importing another group of old photos taken about 10 years ago and they imported in the correct order. What is going on? Any suggestions?
iMac 21.5", OS X 10.11
