Magic Post Thumbnail allows you to automatically generate images for your content from different image banks and with different options.
There are several image banks such as Google Images, Pixabay, Unsplash, Flickr, DALL-E, Pexels, Stable Diffusion or Envato Elements (subscription required).
You can generate these images for your posts, pages and other WordPress post types. These images can be generated either with the Gutenberg block (you can choose the image), either individually or in bulk, by button click, bulk action by selecting multiple posts, by cron or even by enabling compatibility with some other extensions.
