[Plugin: WordPress Form Manager] reCAPTCHA

I understand the idea of reCAPTCHA and it’s a good one, but it can sometimes take a half a dozen (or more times) to find an image that is readable. Just slows things down. Is there a better way? How have others, who have seen it as an issue, dealt with this?
