problem adding photos to icloud shared photo stream
My husband lost the last year of photos as he switched to El Capitan. I have those photos on my mac and want to set up a shared photo stream to send them to him. I can set up the stream with a title, but have not been able to add photos to it from iPhoto. I select some of the photos, have tried both clicking on share and add to, it asks if I want to publish them and I say yes, but the shared stream contains no photos. I have done this before with success, but it is not working now.
Any suggestions.
