Photos in Camera Roll were not copied to My Photo Stream.

My Photo Stream had reached 1,000 photos. I thought I had read that when ther was a new photo, the oldest photo in My Photo Stream would be deleted to make room for the new photo.

This didn't happen. Instead My Photo Stream did not get anymore new photos.

I deleted all photos in My Photo Stream and now a new photo will appear in both the Camera Roll and My Photo Stream.

Now I want to get the newer photos (that failed to be copy to My Photo Stream in the past) to my iMac.

HOW?

iPhone 4S. IOS 7.0.3.

iMac OS X 10.9.1. iPhoto 9.5.1

Both iPhone and iMac connected to iCloud.
