Getting the width and height of an Image

So I have a element and I want to get the image’s height and width property, however this is my css:

let h = Number(window.getComputedStyle(document.getElementById('image')).getPropertyValue('height').replace('px',''));
let w = Number(window.getComputedStyle(document.getElementById('image')).getPropertyValue('width').replace('px',''));
    z-index: 0;
    display: block;
    top: 0px;
    margin-left: auto;
    margin-right: auto;

    max-height: 100%;
    max-width: 100%;

    position: absolute;
    align-self: center;

    margin: auto;
    left: 0;
    right: 0;
<img src="src.jpg" id="image">

as you can see i didn’t set a height and width property because I don’t want the image to have a fixed width and height, so someone introduced me to use:


and so I did, but it is not accurate from my experience:


let h = Number(window.getComputedStyle(document.getElementById('image')).getPropertyValue('height').replace('px',''))
let w = Number(window.getComputedStyle(document.getElementById('image')).getPropertyValue('width').replace('px',''))

here is the screenshot of the results it logged:

and here is the screenshot of the actual width and height of the element:

as you can see the image is 670 x 514 but it logged 459 as its height, anyone can help me with this problem?
