This article illustrates JavaScript's simple method to switch images by mouse movement. To share for your reference, the details are as follows:

function showDaTu(src){
document.getElementById("defaultImg").src=src;
}
</script>
<img src="images/wall1.jpg" id="defaultImg">

<img src='images/wall_s1.jpg' onmouseover="showDaTu('images/wall1.jpg')">
<img src='images/wall_s2.jpg' onmouseover="showDaTu('images/wall2.jpg')">
<img src='images/wall_s3.jpg' onmouseover="showDaTu('images/wall3.jpg')">
<img src='images/wall_s4.jpg' onmouseover="showDaTu('images/wall4.jpg')">
<br> As the picture is large, please wait for the picture to load... Then mouse over the small picture will switch.
