## 説明

ThumbAPI for WordPress turns your post title into a production-ready featured image
with a single click. No template design, no image editing, no extra steps in your
publishing flow.

The plugin adds a panel to the post editor (both the block editor and the classic
editor). When you click **Generate featured image**, the current post title is sent
to your ThumbAPI account, the returned image is uploaded to the Media Library, and
it is set as the post’s featured image automatically.

#### Features

 * One-click featured image generation from the post title
 * Block editor sidebar panel and classic editor meta-box integration
 * Five output formats: Blog post (1200×630), YouTube (1280×720), Instagram (1080
   ×1080), X (1200×675), LinkedIn (1200×627)
 * Three image styles: faceless, with personal photo, with logo
 * Generated images go through the standard WordPress Media Library — full thumbnail
   sizes are generated automatically
 * No bundled scripts or styles loaded outside the post editor and the plugin’s 
   own settings page

#### What you need

 * A ThumbAPI account and an API key from [app.thumbapi.dev](https://app.thumbapi.dev)
 * For “With image” or “With logo” styles, upload your personal photo or logo once
   in your ThumbAPI dashboard

#### External services

This plugin sends data to **ThumbAPI** (`https://api.thumbapi.dev`), which is a 
paid third-party service operated by ThumbAPI. When you click **Generate featured
image**, the plugin sends the post title, your selected format, and your selected
image style to the ThumbAPI `POST /v1/generate` endpoint, authenticated with the
API key you saved in the plugin settings. ThumbAPI returns a generated image which
the plugin then stores in your WordPress Media Library.

 * Service: ThumbAPI
 * Endpoint: `https://api.thumbapi.dev/v1/generate`
 * Data sent: post title, output format, image style, your API key (as `x-api-key`
   header)
 * Terms of service: [https://thumbapi.dev/terms-of-service](https://thumbapi.dev/terms-of-service)
 * Privacy policy: [https://thumbapi.dev/privacy-policy](https://thumbapi.dev/privacy-policy)

The plugin does not contact any other external services.

## FAQ

### Do I need a paid ThumbAPI plan?

You need a ThumbAPI account and an API key. Pricing is set by ThumbAPI; see [thumbapi.dev](https://thumbapi.dev)
for current plans.

### What happens to the generated image?

It is stored in your Media Library exactly like any other upload. You can edit, 
replace, or delete it like any other attachment.

### Does it overwrite an existing featured image?

Yes — clicking the button always sets the new generated image as the featured image.
Your previous featured image stays in the Media Library and can be reassigned.

### Can I use my own saved photo or logo?

Yes. Upload your personal photo or logo once in the ThumbAPI dashboard, then pick
the matching style (“With image” or “With logo”) in the plugin panel.

### Does the plugin support the classic editor?

Yes. A small panel is added below the standard Featured Image meta box.
