How can I write the content of a variable in image src while using document.getElementById?

I have the following code

document.write("<img src=./", i, ".png width='100px' height='100px'>");
document.write("<img src=./", x, ".png width='100px' height='100px'>");
document.write("<img src=./", y, ".png width='100px' height='100px'>");`

and I want to use the src in getElementById(myImg).InnerHTML.

I tried this

document.getElementById("myImg").innerHTML.src = "./", i, ".png width='100px' height='100px'>";

But It’s not working

What is the proper way to write it?

>Solution :

Change the src, not InnerHTML.src. You can see the answer in this question.
and you need to set the width height with style

document.getElementById("myImg").src=`./${i}.png`;
document.getElementById("myImg").style.width="100px";
document.getElementById("myImg").style.height="100px";
