New pictures imported from my camera to Photos are not being pushed to My Photo Stream
It used to work fine in iPhoto.
I would import images from my digital camera to my Mac and they would also move automatically into My Photo Stream I could then see them on my iPhone and iPad.
However, moving over to Photos has stopped this from working. Pictures I take on my iPhone and iPad are being put into My Photo Stream and I can see them on my Mac, but it won't work the other way around as it did before.
Any ideas or help appreciated.
MacBook Pro with Retina display, OS X El Capitan (10.11.3)
