The whole Google Photo infrastructure has other weirdnesses. Photos/images that I share with Hangouts don't show up in Google Photos. Previously I could remove them with Google+ Photos, but since that was shut down, I used Picasa web albums to remove Hangouts images. Another interesting thing that I noticed is that some photos are not added to Google Drive if you upload them to Google Photos and have the Google Drive functionality enabled. Turns out it's exactly the photos that I already shared with Hangouts. Their whole photo story is a mess.
