hello
i found this very useful, it gave me a good start on captcha decoding, i'm planning to use opencv+neurolab for image processing and decoding, its gonna be difficult because theres very fancy background and lines thru the letters with multiple font.
this is a nice blog you have here, pretty neat,but theres SQL injection vulnerability on parameter id, you should check it out.
