Frequently Asked Questions
Common questions about Image Generator – AI Auto Featured Images, Thumbnails & Post Images
No — only for AI prompt-based generation and stock photos. Template-based image creation, including the automatic featured image on publish, runs entirely on your own server using PHP's built-in GD library. No external services, no API calls, no recurring costs — unless you give a template a stock photo or AI image layer. Stock photos need a free API key from Unsplash, Pexels or Pixabay; you only need one.
Create a free key at Unsplash, Pexels or Pixabay, then paste it under Image Generator → Settings → Stock Photos and click Test Connection. You can also define AIMG_UNSPLASH_KEY, AIMG_PEXELS_KEY or AIMG_PIXABAY_KEY in wp-config.php. New Unsplash keys are limited to 50 searches an hour until Unsplash approves them for production.
Yes. Go to Image Generator → Image Templates → Add New to open the Template Studio. Start from one of 10 ready-made designs or a blank canvas, add backgrounds, images, overlays, shapes, patterns, frames and text, and use tags like {title}, {category} or {custom_field:key} so each post gets its own text. Templates are drawn on your server, so they cost nothing to use. You can export a template as JSON and import it on another site.
Background and image layers can show an image from your Media Library, the post's featured image, the first image in the post, the site logo, the site icon, the author's avatar (uploaded to the Media Library), a stock photo picked for the post (Unsplash, Pexels or Pixabay, searched with the post title or your own search text) or an AI image made for the post (from your own prompt). Stock and AI images are fetched once per post, in the background, and reused when you regenerate.
Unsplash, Pexels and Pixabay photos are free to use, and the libraries ask you to credit photographers where you can. The plugin adds a credit with links to the image caption (you can turn this off under Settings → Stock Photos) and always saves it with the image.
Out of the box, the plugin calls OpenAI's Images API using GPT Image 2.5 Flare by default — you can switch to GPT Image 2.5 Sunburst or GPT Image 2 under Image Generator → Settings. Models OpenAI has retired (GPT Image 1, DALL·E 2 and DALL·E 3) are no longer offered; sites that used them switch to GPT Image 2.5 Flare automatically. Developers can swap the endpoint, model, or request body via the aimg_generate_endpoint and aimg_generate_request_body filters — so you can point it at compatible services (Stability AI, self-hosted SDXL via a compatible proxy, etc.).
You pay OpenAI directly for usage, based on the model, image size and quality; see OpenAI's pricing page for current rates. Larger shapes, higher quality and more variations cost more. The plugin itself is free; you only pay your AI provider for the images it creates. To keep costs predictable, limit AI to certain roles, set an hourly limit per user, and use templates for everyday posts. Automatic AI images are only created when a post is published or scheduled, not for drafts.
By default, it's stored in the aimg_settings option in the WordPress database. For maximum security, define AIMG_API_KEY in wp-config.php instead — the settings UI will detect the constant and disable the input field, so the key never sits in the database.
Automatic generation only fires when a post is saved without a featured image. For existing content, open the post in the block editor and use the AI Featured Image panel to generate one on demand. Bulk generation across the entire site is on the roadmap.
Yes. The block editor integration is the plugin's flagship feature. You'll find the ✨ button on Image and Media & Text block toolbars and a dedicated AI Featured Image panel in the document sidebar.
