Can jQuery revert to original src on mouseout?

Context: Im trying to replace an image on mouseover, and return to original on mouseout. WHen i use the original link of the image src, it works. But my problem is that i will have multiple sections of this. I know i can make it work by making a script on each original src and input the image link there, but is there a way to make it return to original img src without adding the hard link of the img?

<div class="col-12 text-center">
    <h3>TITLE</h3>
    <div class="name-wrapper">
        <span id="name1" class="some-name opacity-0">Name 1</span>
        <span id="name2" class="some-name opacity-0">Name 2</span>
    </div>
</div>
<div class="col-12">
    <div class="img-set">
        <img src="images/2023/some-img.jpg" alt="Some Image" />
    </div>
    <div class="hotspots">
        <a href="#" data-src="images/2023/some-img2.jpg" data-target="name1">test1</a>
        <a href="#" data-src="images/2023/some-img3.jpg" data-target="name2">test2</a>
    </div>
</div>

$(".hotspots a").mouseover( function() {

        var value = $(this).attr('data-src');
        $(".img-set img").attr("src", value);

        var target = $(this).data("target");

        var targetName = document.getElementById(target);

        if($(targetName).attr('id') == target) {
            $("#" + target).removeClass("opacity-0");
          }
    })

    $(".hotspots a").mouseout( function() {

        $( '.img-set img' ).attr("src","images/2023/some-img.jpg");

        var target = $(this).data("target");
        var targetName = document.getElementById(target);

        if($(targetName).attr('id') == target) {
            $("#" + target).addClass("opacity-0");
          }
    });

How can i make it so that instead of putting in the actuall src, it would be original src instead.

So i tried with this and the whole thing doesnt work anymore

$(document).ready(function() {

    var original = document.getElementsByClassName(".img-set img").getAttribute("src");

    $(".hotspots a").mouseover( function() {

        var value = $(this).attr('data-src');
        $(".img-set img").attr("src", value);

        var target = $(this).data("target");

        var targetName = document.getElementById(target);

        if($(targetName).attr('id') == target) {
            $("#" + target).removeClass("opacity-0");
          }
    })

    $(".hotspots a").mouseout( function() {

        $( '.img-set img' ).attr("src", original);

        var target = $(this).data("target");
        var targetName = document.getElementById(target);

        if($(targetName).attr('id') == target) {
            $("#" + target).addClass("opacity-0");
          }
    });
    
})
