Featured Image Creator AI

Featured Image Creator AI is the ultimate tool to automatically generate professional-quality featured images for your WordPress posts using cutting-edge AI technology. Whether you need a single image or want to process your entire library, this plugin handles it all with support for top-tier AI providers like OpenAI (DALL-E 3, GPT Image models), Google Gemini (Imagen), and Stability AI (Stable Diffusion 3, SeeDream).

Features

• Style Presets: NEW! One-click looks — Photographic, Flat Illustration, 3D Render, Watercolor, Minimal, Isometric, Cyberpunk, Paper-cut and more. No prompt-writing needed.

• Text & Logo Overlay: NEW! Burn the post title and/or your logo straight onto the image — auto-wrapped headline, font weight, color, position, readability scrim, and corner watermark. Bundled Poppins font; uses Imagick or GD.

• Colour Theme & Per-category Colours: NEW! Set a brand colour that new images are built around, and optionally give individual categories their own colour so different sections of your site stay on-brand in their own shade.

• Image Variations: NEW! Generate several options at once and pick your favorite from a grid. The unchosen images are cleaned up automatically.

• Auto Alt Text: NEW! Writes accessible, SEO-friendly alt text by actually describing the generated image with the provider’s vision model (OpenAI / Gemini), with a title-based fallback.

• Social & Open Graph Images: NEW! Create Facebook/Open Graph (1200×630), Twitter, square and Pinterest sizes from the same generated image — cropped locally with no extra API cost. Optionally sets the Open Graph share image for Yoast SEO / Rank Math, or outputs og:image tags itself.

• Bring Your Own API Key: Use your own OpenAI API key for complete control and transparency

• Single Post Generation: Generate featured images one at a time from the post editor

Using the Creative Features

Styles — Under Settings > AI Enhancements, pick a default look (Photographic, Flat Illustration, Watercolor, Cyberpunk, and more). In the post editor, the Style dropdown lets you override it for a single image. No prompt writing required.

Text & Logo Overlay — Enable it under Settings > Text & Logo Overlay. The post title is drawn on the image by default (use the {title} placeholder), and you can set the font weight, size, color, position, background scrim, and add a logo/watermark in any corner. Rendering happens on your server with Imagick or GD, so it costs nothing extra.

Variations — In the post editor, click Generate Options to create several images at once, then click your favorite to set it. The other options are deleted automatically. The number of options is set under Settings > AI Enhancements (2–8).

Each option uses one API credit.

Auto Alt Text — Turn it on under Settings > AI Enhancements. After an image is set, OpenAI or Gemini describes it and saves the text as the image’s alt attribute for SEO and accessibility. Stability AI falls back to the post title.

Social & Open Graph Images — Enable it under Settings > Social & Open Graph Images and tick the sizes you want (Open Graph 1200×630, Twitter, square, Pinterest). Each generated image is cropped locally into those sizes and saved to the media library — no extra API credits. With Open Graph Image enabled, the share image is set for Yoast SEO / Rank Math, or output as og:image / twitter:image tags when no SEO plugin is active.

Use Cases

• Bloggers who need featured images for every post

• Content marketers managing multiple websites

• Publishers with large content libraries

• Anyone who wants to save time on image creation

Privacy & Data

This plugin uses external AI services to generate images. When you generate an image:

* Your post title (built into the prompt) is sent to the AI provider

* The AI provider generates an image based on your prompt

* The image is downloaded and stored in your WordPress media library

* If Auto Alt Text is enabled, the generated image is additionally sent to the provider’s vision model (OpenAI / Gemini) to produce a description. This is off by default.

* The text and logo overlay is rendered locally on your server — no image data leaves your site for that step

* Social / Open Graph sizes are cropped locally from the generated image — no image data leaves your site for that step

* No other data is sent to external services

Your API key is encrypted and stored securely in your WordPress database.
