What is the recommended approach for updating images on a webpage without requiring multiple reloads?

When updating images on a webpage without requiring multiple reloads, the recommended approach is to use AJAX (Asynchronous JavaScript and XML) to dynamically update the image source without refreshing the entire page. This allows for a smoother user experience and faster loading times. By sending a request to the server to fetch the updated image and then replacing the current image with the new one using JavaScript, you can achieve this functionality seamlessly. 

```php
<!DOCTYPE html>
<html>
<head>
    <title>Update Image Without Reload</title>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
    <script>
        $(document).ready(function(){
            $('#updateImage').click(function(){
                $.ajax({
                    url: 'update_image.php',
                    type: 'GET',
                    success: function(data){
                        $('#myImage').attr('src', data);
                    }
                });
            });
        });
    </script>
</head>
<body>
    <img id="myImage" src="original_image.jpg" alt="Original Image">
    <button id="updateImage">Update Image</button>
</body>
</html>
```

In this code snippet, we have a simple HTML page with an image element and a button. When the button is clicked, an AJAX request is sent to a PHP script (update_image.php) on the server. The PHP script should return the URL of the updated image. The success function in the AJAX call then updates the image source with the new URL without requiring a page reload.
