I've been keeping photos which I display on the blog on the server which hosted my website. So I decide to establish a "Google Photo" account for that purpose, and explore how to put pictures on the blog from that account. It turns out I have to select pictures not "From Google Album Archive," as one might expect, but "From your phone." My phone is about the only electronic thing I have that is not connected to Google. Odd.
I know I can simply upload from my computer to the blog, but then they are stored in some arcane place in hyperspace and I can't do anything else with them. It's beginning to look like the same applies to Google Photos, though, so I'm not sure where to go from here.
