What steps can be taken to ensure that a newly uploaded image is displayed immediately on a PHP forum without needing to refresh the page?

To ensure that a newly uploaded image is displayed immediately on a PHP forum without needing to refresh the page, you can use AJAX to dynamically update the image container on the page after the upload process is complete. This way, the image will be displayed without requiring a full page refresh. 

// PHP code snippet using AJAX to update the image container on the page after upload

// HTML form for image upload
<form id="imageUploadForm" action="upload.php" method="post" enctype="multipart/form-data">
    <input type="file" name="image">
    <input type="submit" value="Upload Image">
</form>

// JavaScript AJAX code to handle form submission and update image container
<script>
    $(document).ready(function(){
        $('#imageUploadForm').submit(function(e){
            e.preventDefault();
            var formData = new FormData(this);

            $.ajax({
                url: 'upload.php',
                type: 'POST',
                data: formData,
                success: function(data){
                    // Update image container with newly uploaded image
                    $('#imageContainer').html('<img src="path/to/uploaded/image.jpg">');
                },
                cache: false,
                contentType: false,
                processData: false
            });
        });
    });
</script>

// Image container where the uploaded image will be displayed
<div id="imageContainer"></div>
