Image Hosting
Google Photos is a storage location for your photos - all your photos - for your eyes only. Google Photos is not an image hosting service. Unless you have special plugins, you cannot use Google Photos to host pictures for use in websites ... except for here in Blogger. I can click the Insert image button, choose Google Album Archive, find the album and then the picture I want and insert it here into a Blogger Blog post. What I'm now testing is, can I use this picture in my Gmail signature on my Android phone? How about this animated .gif that WordPress says is too big for it to host?
