I used the code from this location....
https://www.w3schools.com/howto/howto_js_slideshow.asp
And got it to work ok, for my purposes (with just a few changes) except the initial image doesn't show up. Clicking a dot will make it start, but how do I get it to show the first image automatically.
See: https://www.audioanalogy.ca/studiotour.htm
to see only the dots, but no start image.
I hope someone can help narrow down the glitch.
Thanks
