Magento Captcha image generation replacement

For unknown reason, Magento Captcha module generate and save images for forms like registration, login or contact page. That takes up the disk and does not clean it.

That module replaces image generation with base64 encoding, so image is generated but not saved

Module has been created with Magento 2.4.5, but it could work with other versions
