I use Chrome. Maybe I will try Firefox. I figured out the problem. I had Chrome set at 125%, so the image would not auto fill. Now it does. I simply reverted to 100% and then selected 125% form text only.
Here are some images of abstracts that I spotted at my local grocer. You can see part of the sign, which I did not want. But a couple of days before, there was no sign, so I envisioned a fine abstract but was too late!! The sign went up.
Here is the first with sign.

Here is second, cropped to what I envisioned before sign went up. In fact I wanted the
shadows to project in the white area.

Here is one with longer shadows, but again waited about one hour too long. Lost oblique
shadows which are are much more dynamic. Still looks cool, I think.
