Windows 10: How do I stop Lock Screen slide show collages

The lock screen slideshow randomly creates collages, which are annoying. How do I turn that off? This question has been asked and answered in 2017 but the posted solution does not work. The person asking the question in 2017 replied that it didn't work but I see no followup discussion. Also, how do I change the timing so the delay between photos is longer or shorter?

problems in running slide show in lock screen


Since switching to windows 10 from windows 8.2 I have had problems in running slide show in lock screen. The slide show will only operate when the screen timeout setting is set to 1 minute. All other time settings give a black screen at timeout. Am I missing something?

I use the Lock screen but I do not use anything that can go with it such as slide shows or having aps appear on it. There is a setting in power for it maybe you should look at that in the CP??
