Create a plugin to always display and center the current post’s featured image

Here’s an example of a plugin that you can use to always display and center the current post’s featured image in WordPress:

Step 1: Create a new directory in your WordPress plugins folder. Let’s name it center-featured-image.

Step 2: Inside the center-featured-image directory, create a PHP file (e.g., center-featured-image.php) with the following code:

Step 3: Open the featured-image.php file and add the following code:

<?php
/**
 * Plugin Name: Center Featured Image
 * Description: Automatically displays and centers the current post's featured image.
 * Version: 1.0
 * Author: Maruti Kumar
 */

// Add a filter to the_content
add_filter('the_content', 'center_featured_image');

function center_featured_image($content) {
    // Check if we are inside a single post
    if (is_single()) {
        // Get the current post's ID
        $post_id = get_the_ID();

        // Get the featured image HTML
        $featured_image = get_the_post_thumbnail($post_id, 'full');

        // Check if a featured image exists
        if ($featured_image) {
            // Wrap the featured image in a container div with styling to center it
            $centered_image = '<div style="text-align: center; margin-bottom: 20px;">' . $featured_image . '</div>';

            // Insert the centered featured image at the beginning of the post content
            $content = $centered_image . $content;
        }
    }

    // Return the modified content
    return $content;
}

Step 3: Save the file and Log in to your WordPress dashboard and go to “Plugins” in the left-hand menu.

Step 4: Find “Featured Image Plugin” in the plugins list and click on “Activate”.

Now, whenever you open a post in your WordPress site, the plugin will automatically display and center the featured image at inside of the title post content.
