Well, after spending some time attempting to load photos with "The New Blogger", I have discovered that I cannot. If I drag and drop, I eventually get an empty "photo box" in my post that disappears completely when I move the cursor.
The uploader consistently take several minutes to load (like 12 minutes or more), and the photo selection never displays in the uploader window (43kb jpg file). If I select the blank image box in the uploader window, I get the little "something is happening" thingy for several minutes, then it stops, the select button is de-selected, and no image ever appears.
Also, the legacy Blogger option has vanished.
I'll try again in a week or so and see what happens.
Best of luck to everyone, stay healthy. out there.
