Change image src on the button when hover

I want to change my img src when I hover on the button.

There are few answers that are similar to mine,

but I still can't figure it out.

<button class='Nav' id="Nav_Homepage">
    <img src="./img/Homepage.png" class='img_Nav' id="img_Homepage">
    <label class='lb_Nav'> Homepage </label>
</button>
