I have a ~100 GB photo library on my Mac (mostly photos taken with my dSLR). I put the library in iCloud, choosing to keep originals on the Mac, and all works well. Now I enabled iCloud photo library on my iPhone (a 128GB 6s with ~80 GB still free). I chose "optimize" on the iPhone, as the entire library is too big, but I'd like to be able to view a few GB worth of some of my recent and favourite photos on the phone. It synchronized correctly, but all the photos from my Mac show as thumbnails on the iPhone. When I tap a thumbnail, it does download the full resolution image, so I guess it works as designed. But it's tedious to do it image-by-image, and I'd like to get my favourite albums on the iPhone over WiFi, not having to use cellular data when I feel like showing a picture. And here's the question - is there a way to get an entire album (or, at least, a bunch of selected images) to download as full resoultion images to the iPhone? Kind of like it works with iCloud Music where I can make entire albums or playlists available offline? The ideal would be an option to have e.g. last year's photos download as full resolution automatically (as it worked with iPhoto/iTunes syncing).
