Yeah - you'd have to download and display those... possible but more time consuming. I haven't seen a service which requires captcha on password change before - if that's the case then you have a problem.

Alternatively if you have 30+ paid accounts with some small company, you could ask them for whitelisting your ip. They might be interested in doing this.

deathbycaptcha or some other similar service, used to be one called decaptcher I think but looks like its down now.
