When you insert an image into a page, you can click on the image, click the pencil, and the Image Details dialog has:
[picture goes here]
“Edit Original”, “Replace”
On the right, and in the left middle you have:
Align [ Left ] [ Center ] [ Right ] [ None ]
Size [ Thumbnail – 150 x 150 ][^]
Link To [ None ][^]
The buttons under the image are missing and the Size selection is missing.
BTW: I am comfortable with SQL & editing the database if need be.
