How to increase or decrease images size with new values using input text?

I need to change images size all at once when I enter new values in to Input text, nothing is working for me... I see a lot of similar posts, but again, nothing works :)

Html-

function increaseSize( img, input ) { 

         var myImg = document.getElementById("gr");

         var input = document.getElementById("input-width");

         var input = document.getElementById("input-height");

         img.style.width = input.value + "px";

         img.style.height = input.value + "px";

     }
    // enter code here
     increaseSize( "myImg" );
<div class="grupe" id="gr">

Try this

function increaseSize( ) { 
    var myImgs = document.getElementById("gr");
    var width = document.getElementById("input-width").value;
    var height = document.getElementById("input-height").value;

    myImgs.querySelectorAll('img').forEach(img => {
        img.style.width = width + "px";
        img.style.height = height + "px";
    })
}
<div class="grupe" id="gr">
