LOOS

<p>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.</p>
<p>Generation runs asynchronously through WP-Cron, so saving a post is never blocked by the API call.</p>
<h4>What this plugin does</h4>
<ul>
<li>Builds an API URL from your post title and the site-wide parameters configured on the settings screen.</li>
<li>Resolves the 302 redirect from the API to extract a stable source hash, so identical parameters do not re-generate the image.</li>
<li>Sideloads the JPEG into the Media Library and attaches it as the featured image.</li>
<li>When the title changes, regenerates the image and (optionally) deletes the previous plugin-generated attachment so the Media Library does not accumulate orphans.</li>
<li>Respects manually-set featured images. If the existing featured image was not generated by this plugin, it is never overwritten.</li>
</ul>
<h4>What this plugin does NOT do</h4>
<ul>
<li>It does NOT output an <code>og:image</code> 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).</li>
<li>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.</li>
<li>It does NOT modify the front-end output of your site.</li>
</ul>
<p>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).</p>
<h3>External services</h3>
<p>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.</p>
<p><strong>OG Image Maker API (and its CDN delivery host)</strong></p>
<ul>
<li>Endpoints:
<ul>
<li>API: https://loos.tools/ogimg-maker/api</li>
<li>Generated JPEG delivery (CDN): https://og-cdn.loos.tools/</li>
</ul>
</li>
<li>What is sent:
<ul>
<li>To the API: the post title (as the <code>title</code> query parameter) and the API parameters configured on the plugin settings screen (e.g. <code>type</code>, <code>layout</code>, <code>mode</code>, <code>panel</code>, <code>frame</code>, <code>radii</code>, <code>pattern</code>, OKLCH <code>h</code> / <code>c</code> / <code>l</code>, and resolved <code>head</code> / <code>foot</code> text).</li>
<li>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).</li>
</ul>
</li>
<li>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.</li>
<li>Terms of Service: https://loos.tools/terms/</li>
<li>Privacy Policy: https://loos.tools/privacy/</li>
</ul>
<p>If you do not wish to send data to this service, do not activate the plugin.</p>

<p>Creotec Title Card Images for Open Graph creates a generated JPEG or WebP image for supported<br />
posts, pages, and public custom post types by combining the content title with<br />
the featured image. Oversized featured images are resized to a maximum width of<br />
1200px before the generated image is saved. The generated image is stored in:</p>
<p>wp-content/uploads/creotec-title-card-images-for-open-graph/</p>
<p>The plugin updates Open Graph image metadata for:</p>
<ul>
<li>og:type</li>
<li>og:title</li>
<li>og:url</li>
<li>og:image</li>
<li>og:image:width</li>
<li>og:image:height</li>
<li>og:image:type</li>
</ul>
<p>When Yoast SEO is active, the plugin uses Yoast’s Open Graph filters for the<br />
generated image. On supported singular content, it also checks wp_head output,<br />
replaces existing Open Graph image tags with the generated image tags, and adds<br />
only missing required non-image Open Graph tags. This allows it to work with SEO<br />
plugins and themes that already output Open Graph metadata.</p>
<p>The generated image is refreshed when the post title changes, when the featured<br />
image changes, when the featured image is removed, or when the plugin settings<br />
change.</p>
<h3>Settings</h3>
<p>Go to Settings > Creotec Title Card Images for Open Graph.</p>
<p>Available options:</p>
<ul>
<li>Title position: above, below, or middle of the featured image.</li>
<li>Title text colour.</li>
<li>Title background colour.</li>
<li>Additional text: optional single-line text shown below the title.</li>
<li>Additional text colour.</li>
<li>Title font size, with automatic sizing available.</li>
<li>Additional text font size, with automatic sizing available.</li>
<li>Generated image format: JPEG or WebP when supported by the server.</li>
</ul>
<h3>Admin Posts List</h3>
<p>The plugin adds an Open Graph Image column to the admin posts list. The column uses<br />
icons to show whether a generated image exists, is missing, is stale, or cannot<br />
be generated because the post has no featured image. Missing images are shown as<br />
a neutral status with an action icon to generate the image.</p>
<p>The posts list also includes a Generate Open Graph Images bulk action.</p>
<h3>Notes</h3>
<p>The plugin uses PHP GD to generate images. TrueType text is used when a readable<br />
font is available. Open Sans Bold is bundled and used by default for consistent<br />
rendering across environments. You can provide a specific font with the<br />
creotcog_font_file filter.</p>
<p>The bundled Open Sans font is distributed under the SIL Open Font License in<br />
assets/fonts/OFL.txt.</p>
<p>By default, public post types that support featured images are handled,<br />
including posts, pages, and eligible custom post types. Developers can narrow or<br />
adjust this with the creotcog_supported_post_types filter.</p>
