You can change pictures in the new photos by either clicking the arrows on each side of the photograph or using the right and left arrows on your keyboard. Also, you can close a photograph by clicking on the black "X" on the upper right corner of the screen and choose another one from the icons on your computer. Another square will appear in the upper right corner of the computer screen. Clicking this will get rid of most of the backround. Unfortunately, you cannot use it reliably to change pictures.
The new photographs show many things that I did not show before. They include many different settings of stained glass, the charred earth near my daughter's California home, a magnificent model train layout, and a few surprises.
