You need to sign up for a Filestack account at https://www.filestack.com/signup- start/. Once you have an account, login to the Filestack DevPortal at https://dev. filestack.com/ to get your API Key and generate your Policy and Signature keys. ### Will this overwrite my existing alt text? The plugin only generates alt text for images missing descriptions. Existing alt text is always preserved. ### Can I pause the bulk processing? Yes! You can pause the processing at any time and resume it later. Your progress is maintained. ### How many images can I process at once? The plugin processes images in batches of 5 to avoid server timeouts. You can process as many images as you need – the plugin will handle them automatically in batches. ### What happens if the API fails? The plugin logs any errors and continues processing the next image automatically. When complete, you get a full summary of processed, skipped, and error counts. ## Reseñas No hay reseñas para este plugin. ## Colaboradores y desarrolladores “Filestack AI Image Alt Text Generator for WP” es un software de código abierto.
