Captcha question.

So i'm having a problem with getting the the recaptcha challenge URL to give me the correct image url. When I load the page with this:



In the page source it gives me a URL to which that challenge is:



The image i was first given was seperate to the image i have recieved in the url stating it was the challenge url. In the source code all the information about the captcha it gives me is here



So I thought I should ask if anybody else has ran into this problem, let alone know a way how trk around it.

If you open the javascript file the page is linking to, it contains a line like:

    challenge : '03AHJ_VutwCx_OTB6TbZmw_nFMVOAv0X35u3lLoXJQs5dAP5wapEnKzTyphppT5MLskiCibxnb68Bg9JmIAWBVoP1WW9lhwWBlJvXrXT05tnp4btZ2BGaSJKAvte5qPOpMyOk3U79TzOc6eS7vnG8zVr0A6niilfCVy5tF1tJdOlU1VNO2dvWUPCI',

If you append the text (eg. 03AHJ...) to the end of "http://www.google.com/recaptcha/api/image?c=", you get the image url.

I could have sworn i've done that, I must have been screwing around with the other url they provide which was the "noscript?k=" opposed to "challenge?k=" Its been a long day haha

BTW, if you use the noscript iframe, the same string is in the "recaptcha_challenge_field" tag, eg:

<input type="hidden" value="03AHJ_VusittytpRK4XmYkNPFw928HObpD6rAFvgv5n1gjPW6eZ3v47vpHgPcLPUUictUAW9YRU8lkVQ3RtXVpJ6HaRDaXwuzcvuhqPgTAvJwhW0unymACDrY8PdU_XV5UoC_6a51OgO8QsQBFN7sL58TP90VP14fRnOpLiWPkZ0svvlu1Hw72jLo" id="recaptcha_challenge_field" name="recaptcha_challenge_field">

or between the img tags:

<img width="300" height="57" src="image?c=03AHJ_VusittytpRK4XmYkNPFw928HObpD6rAFvgv5n1gjPW6eZ3v47vpHgPcLPUUictUAW9YRU8lkVQ3RtXVpJ6HaRDaXwuzcvuhqPgTAvJwhW0unymACDrY8PdU_XV5UoC_6a51OgO8QsQBFN7sL58TP90VP14fRnOpLiWPkZ0svvlu1Hw72jLo" alt="">
