Description

AI Featured Image Generator lets you create AI-powered featured images right from the WordPress editor. Hit “Generate Featured Image” on any post, and the plugin uses OpenAI (or Google Gemini for Pro users) to generate a unique image based on your post title, chosen style, and an optional custom prompt. You can also choose whether to allow text on the generated image or keep it text-free.

Every generated image automatically gets alt text set in the WordPress media library — improving SEO and accessibility without any extra work. You can configure the alt text source (post title, prompt, or a custom template with placeholders like {title}, {style}, and {site_name}), or turn it off entirely from the General settings tab.

Free users get a Bulk Generate tab to create featured images for up to 5 posts per batch (50 images lifetime). Pro users unlock unlimited bulk generation, advanced filters, Gemini support, and an AI Image Generator block for adding inline images directly inside the Gutenberg editor. Everything is managed from one settings hub.

How much does it cost?

The plugin itself is free, but you’ll need to pay for API usage according to OpenAI’s pricing (pay per image generation).

Pro users with Gemini: Gemini 2.5 Flash uses 1290 tokens per image, Gemini 3.1 Flash and Gemini 3 Pro vary by resolution (1K/2K/4K).

Can I switch between providers?

Pro users can switch between OpenAI and Google Gemini. Simply go to AI Featured Image in the admin menu, select your preferred provider, and enter the appropriate API key. The settings page will automatically show only the relevant options for your selected provider.

Is there a limit to how many images I can generate?

The limit depends on your API plan and quota with your chosen provider. The plugin generates one image per request.

What AI models are available?

Free Version (OpenAI):
– ChatGPT Image Latest: Always points to the newest ChatGPT image model, so you automatically get improvements
– GPT Image 1.5: Strong quality and accurate text, cheaper and faster than GPT Image 1

Can I create my own custom styles? (Pro)

Yes! Pro users can define custom image styles with a name and a prompt description (e.g. “in a dreamy impressionist style”). Custom styles appear under a “Custom” group in all style dropdowns — in the post editor, the settings page, and the inline image block — and work exactly like built-in styles.

To add a custom style:

  1. Go to AI Featured Image Settings Featured Images tab
  2. Scroll to the “Custom Styles” section
  3. Click “Add Style”, enter a name and a prompt description, then save
  4. Your custom style will immediately appear in all style dropdowns

What aspect ratios does Gemini support? (Pro)

Pro users with Google Gemini get access to 10 aspect ratios with model-specific resolutions:

All Models (1:1, 3:4, 4:3, 9:16, 16:9):
– Always supported by both Gemini models

Additional Ratios (2:3, 3:2, 4:5, 5:4, 21:9):
– Full support varies by model

– WebP (Recommended): Best compression and quality balance
– PNG: Lossless format, good for graphics with sharp edges
– JPEG: Widely compatible, good for photographs

Google Gemini (Pro only):
– PNG (Fixed): Gemini generates images in PNG format only

How does quality control work?

OpenAI (Free & Pro):
– Set default quality (1-100) in the plugin settings under Featured Images Output Settings
– Higher quality produces larger file sizes but better image detail
– Default quality is set to 90 for optimal balance

Google Gemini (Pro only):
– Gemini 2.5 Flash: Fixed resolution per aspect ratio (quality control not applicable)
– Gemini 3.1 Flash: Choose between 1K, 2K, or 4K resolution options
– Gemini 3 Pro: Choose between 1K, 2K, or 4K resolution options

Can I generate images inside the Gutenberg editor? (Pro)

Yes! Pro users can generate inline images directly inside the Gutenberg editor using the AI Image Generator block. Simply add the “AI Image Generator” block from the Media category in the block inserter, enter your prompt, and generate images anywhere in your content. The block supports all the same styles, aspect ratios, and settings as featured images. Configure default settings for inline images in the Inline Images tab on the plugin settings page.

How does auto alt text work?

When you generate any AI image (featured, inline, or bulk), the plugin automatically sets the alt text field on the attachment in the WordPress media library. This means your images are immediately accessible to screen readers and better indexed by search engines — no manual work needed.

You can configure auto alt text from AI Images Settings General Alt Text:

  • On/Off toggle: Enable or disable the feature entirely (enabled by default)
  • Post Title (default): Uses the post title for featured and bulk images, and the prompt for inline images
  • Image Prompt: Uses the generation prompt as alt text
  • Custom Format: Build your own template using placeholders — {title} (post title), {prompt} (generation prompt), {style} (style name, e.g. “Realistic”), and {site_name} (your site name). Example: {title} - {style} style - {site_name}
  • Overwrite on Regeneration: When disabled (default), manually edited alt text is preserved when you regenerate a featured image. Enable this option if you want fresh auto-generated alt text each time.

Does it work with custom post types? (Pro)

Yes! Pro users can enable AI image generation for any public custom post type:

  1. Go to AI Featured Image in the admin menu
  2. Scroll to the “Enabled Post Types” setting
  3. Check the boxes for the post types where you want to enable the image generator
  4. Save settings

The AI Featured Image Generator panel will now appear in the editor for all selected post types. Free version users are limited to Posts and Pages only.

great plugin

December 4, 2025
This plugin is a real time saver. Instead of going to ChatGPT, downloading the image, resizing it, uploading it, and then using Photoshop to add text, it does everything for you with one button directly inside the post editor. The simple image quality slider also helps control how the image looks and how large it is, which is great for SEO.

I really liked it

I’ve been using the AI Featured Image Generator plugin for a while, and it’s honestly impressive. The integration is smooth and intuitive — just one click and you get a beautiful AI-generated featured image that perfectly fits your article’s topic. Honestly, I can’t think of a single reason why someone wouldn’t use it. It just makes the whole publishing process faster, easier, and more creative.

Amazing Experince
