Do you need to implement it in a library, or can you call it as a web service? Reliable services include google recaptcha ( http://www.google.com/recaptcha) and OpenCaptcha ( http://www.opencaptcha.com/). Flicker and others also provide similar services...so you can implement a couple services to both randomize the source (theoretically increases security) and provide HA.
