To use a URL to generate a captcha image, you must add the bundle's routing configuration to your config/routes.yaml file:

Since the session key is transported in the URL, it's also added in another session array, under the whitelist_key key, for security reasons

Form Theming

The widget support the standard Symfony theming, see the documentation for details on how to accomplish this.

Image creation
