Where is this setting win11

[chili]

I think i maybe going stupid, when i click on my desktop and select personalise i have a nice there setup and also in the colors option i have selected dark
ok so far.
Now when i do not touch anything for a couple of minutes my screen starts to display images for a screensaver i guess, it cycles through these images
but the images in question are not what i want to display. buggered if i can remember how to unscrew this.
someone help an old man.

Have you tried:

personalisation > lock screen?

Personalisation, personalise your background, click on the dropdown and change from picture to slideshow.
