In albums how do you change the timing of each slide in the slideshow

There are no controls to change the timing of an instant slideshow from an album.

You can only adjust the timing for individual slides or all slides, when you create a slideshow project.

It will depend on the Theme for the slideshow and your system version, what will be possible.

You can set the speed for individual slides only in the themes Classic and Ken Burns.

For example - using Ken Burns: Click the stopwatch icon in the sidebar to the right of the slideshow window:

You can only change the time for the complete slideshow. Each slide is shown for the same amount of time.

Right hand side - stop watch icon.
