Image position movement by style.top and style.left value in JavaScript

We can assign coordinates to position an image by changing its style.left and style.top property value in JavaScript. We can keep changing these values to move the image to different location. Here is the code to set these values.

document.getElementById('i1').style.left="200px";
document.getElementById('i1').style.top="100px";

By using above concepts we will try to change position of an image by moving it from left to right , top to down and vice-versa.
Demo of moving image
The code is here

<html>
<head>
<title>Demo of Image position style.top and style.left </title>
<link rel="stylesheet" href="../images/all11.css" type="text/css">
<script language='JavaScript' type='text/JavaScript'>
<!--
function move_img(str) {

switch(str){
case "down":
document.getElementById('i1').style.top=600 + "px";
break;

case "up":
document.getElementById('i1').style.top=100 + "px";
break;

case "left":
document.getElementById('i1').style.left=200 + "px";
break;

case "right":
document.getElementById('i1').style.left=800 + "px";
break;

}
}
//-->
</script>
</head>
<body>
<img src=images/help.jpg id='i1' 
 style="position:absolute; left: 500; top: 100;">
<br><br><br><br>
<input type=button onClick=move_img('up') value='Up'>

Example: Making an Image Draggable

Draggable Image: Demonstrates how to allow users to drag and reposition an image interactively with the mouse, enhancing user experience.
DEMO : Dragging image by Mouse

<img id="myImage" src="image.jpg" style="position: absolute; 
	top: 50px; left: 50px;" draggable="true">

<script>
let img = document.getElementById('myImage');
img.onmousedown = function(event) {
  let shiftX = event.clientX - img.getBoundingClientRect().left;
  let shiftY = event.clientY - img.getBoundingClientRect().top;

  function moveAt(pageX, pageY) {
    img.style.left = pageX - shiftX + 'px';
    img.style.top = pageY - shiftY + 'px';
  }

  function onMouseMove(event) {
    moveAt(event.pageX, event.pageY);
  }

  document.addEventListener('mousemove', onMouseMove);

  img.onmouseup = function() {
    document.removeEventListener('mousemove', onMouseMove);
    img.onmouseup = null;
  };
};

img.ondragstart = function() {
  return false;
};
</script>
