I posted this thread, then realized I'd only attached the images and not the script file. I clicked Edit then clicked the "More" button to get the real editor, then dragged the script file to attach it. When I Save the changes, the forum sometimes says I need to login (but I am not logged out), and other times it says "Input error". In neither case does it actually save the change. I tried a couple times, including after restarting the browser. This is the latest Chrome on Win10 Pro. I finally gave up and added a new post to the thread.
