Automating creating slide shows of Photos in Windows10

[Nadarajah]

Hi

I have a big collection of photos of various kinds - wildlife, holiday, family etc. 

I would like to create slide shows to view via a browser.  I can do that manually from the examples 
https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_slideshow 
https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_slideshow_auto 
https://www.w3schools.com/howto/tryit.asp?filename=tryhow_js_slideshow_multiple 
  
given in this link How To Create a Slideshow (w3schools.com)

Photos are grouped in folders on Computer running Windows10.

At the moment I can only do it manually by individually adding photos to the html file and the necessary codes. I am thinking there must be a way to automate this process using js or something else.  But do not now how to do that. 

Hope you understand my problem.

Would you be able to help and suggest any solution?

Thanks
Thiru
