Help! I want images to appear while scrolling

Hello all, basically what I want (I believe) should be simple, but I have spent some time looking for a solution and have not found a way. FYI I know nothing about coding:

I have a section in a webpage I am designing where I want the user to navigate in a way where they are scrolling down, and images start appearing as they scroll. I can’t do it with the background option since most of the images overlap. I am attaching an extra zoomed out image of the entire part that I want to have. Basically, every step or section should appear as the user scrolls down on the webpage.

You can make them hidden on load, add anchors to the desired scroll spots, and do something like:

$w.onReady(() => {
 $w('#anchor1').onViewportEnter(event => {
  $w('#image1').show();
 })
 $w('#anchor2').onViewportEnter(event => {
  $w('#image2').show();
 })
 //etc...
})
