<img src = unknown/>.

My img array is an url array not in any folder.

Here's what i already have

  slideShow();
  const diapoImages = [

  ];

  var imgDiv = document.getElementById("header");

  if (counter < diapoImages.length) {
    var img = diapoImages[counter];
    imgDiv.innerHTML = `<img src=${img}/>`;
    counter += 1; 
  }
  else {
    counter = 0; 
  }
  setTimeout(slideShow, 5000)
}

here's the HTML

You should create the image tag using document.createElement("img"). Then, you should set the src of image tag. At the end of the function, you should append the image tag into the div tag.

function slideShow() {
        var counter = 0;
            slideShow();
            const diapoImages = [

    var imgDiv = document.getElementById("header");
    var image = document.createElement("img")

            if (counter < diapoImages.length) {
                var img = diapoImages[counter];
                imgDiv.appendChild(image)
                counter += 1;
                image.src = img 
            }
            else {
                counter = 0; 
            }
        }
    }
    setTimeout(slideShow, 5000)

I don't know about innerHTML error, but I could see two important points that maybe help you.

The line 3 (slideShow();) causes recursive calls.
Whenever the function is invoked, line 2 (counter = 0;) will reset the value. So the second image will never be rendered.

function slideShow(counter = 0) {
  const diapoImages = [

  ];

  var imgDiv = document.getElementById("header");

  if (counter < diapoImages.length) {
    var img = diapoImages[counter];
    imgDiv.innerHTML = `<img src=${img}/>`;
    counter += 1;
  } else {
    counter = 0;
  }

  setTimeout(() => slideShow(counter), 5000)
}

slideShow();

<div id="header"></div>
