<h3>External services</h3>
This plugin can connect to the WordPress avatar system, which commonly uses Gravatar, when the Featured Image Generator is configured to include the post author’s avatar.
When the avatar option is enabled, the plugin requests the author’s avatar URL while showing the featured-image preview in the WordPress admin and while generating a featured image for a post or page. WordPress builds that avatar URL from the author’s user account email address according to the site’s normal avatar settings. The plugin downloads the avatar image from that URL so it can draw the circular author avatar into the generated featured image. If the avatar option is disabled, or if no avatar URL is available, the plugin does not request the avatar image and uses a local placeholder shape instead.
The avatar service is provided by Gravatar/Automattic:

<h3>Built for scale and complete image SEO workflows</h3>
Many AI alt text plugins work well for smaller libraries, but become slower, more expensive, or harder to scale when you need bulk processing across a large number of images.
Some tools rely on external model limits or generic workflows that are not built for large WordPress media libraries. Others focus only on adding alt text in the media library and do not offer a broader image optimization workflow.
Alt Magic is built differently. It is designed for fast, stable, high-volume processing with better cost efficiency at scale.
With Alt Magic, you get: 
* Faster bulk processing for large image libraries 
* Better value on high-volume workloads 
* Support for both existing images and new uploads 
* AI image renaming for both existing images and new uploads 
* A broader WordPress image SEO workflow from one plugin
This makes Alt Magic a strong fit for WooCommerce stores, publishers, agencies, directories, and other image-heavy websites.
