Uniqueness in image generation
Personalized content

For agencies and SaaS companies, this feature may serve as an additional paid service.

What You’ll Need Before You Start

Make sure you have the following requirements ready:

Prerequisites

WordPress installation
Administrator access
Basic PHP knowledge
JavaScript understanding
WordPress plugin development experience
Access to a WordPress AI Client setup
AI API credentials

Recommended development environment:

PHP 8.1+
WordPress 6.5+
LocalWP or XAMPP
VS Code

Step 1: Create the Plugin Structure

Start by creating a new plugin folder inside your WordPress plugins directory.

wp-content/
└── plugins/
    └── ai-image-generator/
        ├── ai-image-generator.php
        ├── assets/
        │   ├── js/
        │   └── css/
        ├── includes/
        └── templates/

Create the main plugin file:

<?php
/**
 * Plugin Name: AI Image Generator
 * Description: Generate AI images using WordPress AI Client.
 * Version: 1.0
 * Author: Your Name
 */

if (!defined('ABSPATH')) {
    exit;
}

Activate the plugin from the WordPress admin panel.

At this stage, you have a basic plugin framework ready.

Step 2: Register an Admin Menu

Next, create a dedicated page where users can generate images.

Add the following code:

add_action('admin_menu', 'aig_add_admin_menu');

function aig_add_admin_menu() {
    add_menu_page(
        'AI Image Generator',
        'AI Images',
        'manage_options',
        'ai-image-generator',
        'aig_admin_page',
        'dashicons-format-image'
    );
}

function aig_admin_page() {
    include plugin_dir_path(__FILE__) . 'templates/admin-page.php';
}

This creates a new menu item called AI Images in the WordPress dashboard.

Step 3: Build the User Interface

Now let’s create a simple image generation form.

Inside templates/admin-page.php:

<div class="wrap">
    <h1>AI Image Generator</h1>

    <textarea
        id="imagePrompt"
        rows="5"
        cols="70"
        placeholder="Describe the image you want..."
    ></textarea>

    <br><br>

    <button id="generateImage" class="button button-primary">
        Generate Image
    </button>

    <div id="imageResult"></div>
</div>

The interface remains intentionally simple because users value speed and clarity when generating images.

Example Prompt

A futuristic city skyline at sunset with flying cars,
ultra-realistic, cinematic lighting.

The more detailed the prompt, the better the generated image quality.

Step 4: Enqueue JavaScript Files

Create a JavaScript file for handling AJAX requests.

In your main plugin file:

add_action('admin_enqueue_scripts', 'aig_enqueue_scripts');

function aig_enqueue_scripts() {
    wp_enqueue_script(
        'aig-script',
        plugin_dir_url(__FILE__) . 'assets/js/script.js',
        ['jquery'],
        null,
        true
    );

    wp_localize_script(
        'aig-script',
        'aig_ajax',
        [
            'ajax_url' => admin_url('admin-ajax.php'),
            'nonce' => wp_create_nonce('aig_nonce')
        ]
    );
}

This makes AJAX communication possible between the browser and WordPress.

Step 5: Connect to the WordPress AI Client

Now comes the exciting part: generating images through AI.

Create an AJAX endpoint:

add_action('wp_ajax_generate_ai_image', 'generate_ai_image');

function generate_ai_image() {

    check_ajax_referer('aig_nonce', 'nonce');

    $prompt = sanitize_text_field($_POST['prompt']);

    $response = wp_remote_post(
        'YOUR_AI_ENDPOINT',
        [
            'headers' => [
                'Authorization' => 'Bearer API_KEY',
                'Content-Type' => 'application/json'
            ],
            'body' => json_encode([
                'prompt' => $prompt,
                'size' => '1024x1024'
            ])
        ]
    );

    wp_send_json_success(
        json_decode(
            wp_remote_retrieve_body($response),
            true
        )
    );
}

This endpoint receives a prompt, sends it to the AI service, and returns the generated image data.

Step 6: Handle the Frontend Request

Now create the JavaScript functionality.

Inside assets/js/script.js:

jQuery(document).ready(function ($) {

    $('#generateImage').on('click', function () {

        let prompt = $('#imagePrompt').val();

        $.post(
            aig_ajax.ajax_url,
            {
                action: 'generate_ai_image',
                prompt: prompt,
                nonce: aig_ajax.nonce
            },
            function (response) {

                if (response.success) {

                    $('#imageResult').html(
                        '<img src="' +
                        response.data.image_url +
                        '" width="500">'
                    );

                }
            }
        );

    });

});

Now users can submit prompts and receive AI-generated images without reloading the page.

Step 7: Save Generated Images to the Media Library

A major usability improvement is automatically storing generated images inside WordPress.

Use:

require_once(ABSPATH . 'wp-admin/includes/file.php');
require_once(ABSPATH . 'wp-admin/includes/media.php');
require_once(ABSPATH . 'wp-admin/includes/image.php');

Download the image:

$image_url = $response_data['image_url'];

$tmp = download_url($image_url);

$file_array = [
    'name' => 'generated-image.jpg',
    'tmp_name' => $tmp
];

$attachment_id = media_handle_sideload(
    $file_array,
    0
);

Benefits include:

Easy image management
SEO-friendly image URLs
Media library organization
Future image editing support

This creates a seamless WordPress experience for users.

Step 8: Improve the User Experience

A professional plugin should provide visual feedback.

Add a loading indicator:

$('#imageResult').html(
    '<p>Generating image...</p>'
);

You can also include:

Progress indicators
Prompt history
Image regeneration
Download buttons
Favorite images

These enhancements make the plugin feel polished and production-ready.

Step 9: Add Security Best Practices

Security should never be overlooked when working with AI APIs.

Always:

Validate User Input

sanitize_text_field($prompt);

Verify Nonces

check_ajax_referer();

Escape Output

esc_url();

Limit Requests

Consider implementing:

transient rate limiting

to prevent abuse and unnecessary API expenses.

A secure plugin protects both your users and your AI budget.

Step 10: Optimize for Performance

AI image generation can be resource-intensive.

Here are proven optimization techniques:

Cache Results

Store previously generated images for repeated prompts.

Compress Images

Use WordPress image optimization plugins.

Queue Requests

For high-traffic websites, process image generation asynchronously.

Lazy Load Images

Improve dashboard performance by loading images only when needed.

These improvements become increasingly important as your plugin scales.

Real-World Use Cases

Here are some practical examples of how businesses can use an AI image generation plugin.
