Yes, sorry. I was just thinking outloud.
I had dropped in a png file and it came up just fine. It all looked good, but then disappeared. When I tried to do the same thing again, I was advised that even though I then put some text in, that it showed as empty.
Instead, of course, I did it the way one should. Attach a file. It was still a png but I said it was a photo. Came out well.
So Grandad, I hope that is somewhat clear.
