Ok Joe, I did test, a way, anyway to force the 16 images to the iphone from the desktop Photos. Share, and then software makes you create a new album. And even then it did not come up on iphone, I have to click share, then iphone chuggs along updating over 15 min. and even then is not in "ALL PHOTOS", only a special share folder.

But, they do appear in Instagram. So it works...

Bottom, line, I was very excited, to not have to plug in my iphone to the desktop to add photos. I could just drag them into photos-desktop- and they would efficiently make it to the iphone, but it does not seem a reality. I do have all the settings synced well per your nice screenshots in this thread.

So there is this workaround, but it's a few clicks a wait, a bit better than cording in the iphone to the desktop hub.

Conversely, When I take one image on an iphone that flies everywhere instantly, but dragging images into photos desktop.. real sluggish bummer of inefficiently with icloud.

Still this is all great info, thanks, any final ideas on this?
