The code is the code provided on the tutorial page I linked.
Literally copy and pasted the html, css, and js.
I want to know what line in that code is supposed to solve my problem, or if there's another method.
On the tutorial for an image gallery slideshow (https://www.w3schools.com/howto/howto_js_slideshow_gallery.asp) the example starts with the first image enlarged.
The code they provided doesn't apply that to my website, I have to select an image to enlarge it, is there something I can add?
Thanks
