我真的很喜欢 Securimage 看起来确实不错，不需要第三点第三方外部服务或javascript（除非您启用了新的图片功能）。也可以将其配置为提供音频验证码以实现可访问性。

I really like Securimage is seems to work really well and does not require a third-party external service or javascript (unless you enable the new image feature). Also it can be configured to provide audio captcha for accessibility.
