LOOS Featured Image Automator

LOOS Featured Image Automator builds an OG Image Maker URL from your post title and site-wide API parameters defined on the settings screen, fetches the generated 1200×630 JPEG, sideloads it into the WordPress Media Library, and attaches it to the post as the featured image.

Generation runs asynchronously through WP-Cron, so saving a post is never blocked by the API call.

What this plugin does

• Builds an API URL from your post title and the site-wide parameters configured on the settings screen.
• Resolves the 302 redirect from the API to extract a stable source hash, so identical parameters do not re-generate the image.
• Sideloads the JPEG into the Media Library and attaches it as the featured image.
• When the title changes, regenerates the image and (optionally) deletes the previous plugin-generated attachment so the Media Library does not accumulate orphans.
• Respects manually-set featured images. If the existing featured image was not generated by this plugin, it is never overwritten.

What this plugin does NOT do

• It does NOT output an og:image meta tag. The image is set as the featured image only. Your theme or SEO plugin is expected to read the featured image and output the meta tag (this avoids duplicate output when combined with SEO plugins).
• It does NOT provide any per-post UI (no meta box, no Gutenberg sidebar). The only per-post value is the post title; all other API parameters are managed globally on the settings screen.
• It does NOT modify the front-end output of your site.

This plugin depends on a third-party service (operated by LOOS Inc.) to generate featured images. See the “External services” section below for the full disclosure (endpoints, what is sent, and when).

External services

This plugin relies on the following third-party service operated by LOOS Inc. to generate featured images. Activating the plugin and saving a post on a target post type causes data to be sent to this service.

OG Image Maker API (and its CDN delivery host)

• Endpoints:
  • API: https://loos.tools/ogimg-maker/api
  • Generated JPEG delivery (CDN): https://og-cdn.loos.tools/
• What is sent:
  • To the API: the post title (as the title query parameter) and the API parameters configured on the plugin settings screen (e.g. type, layout, mode, panel, frame, radii, pattern, OKLCH h / c / l, and resolved head / foot text).
  • To the CDN: only the standard HTTP request to download the generated JPEG (no plugin-specific payload other than the URL path identifying the image).
• When data is sent: When WP-Cron processes a queued generation job for a target post. The plugin issues a HEAD request to the API to obtain a 302 redirect to a CDN URL, then downloads the generated JPEG from the CDN into the WordPress Media Library. Repeated requests for the same source hash are skipped.

If you do not wish to send data to this service, do not activate the plugin.
