    It cracks google mail and a few other sites that I have tried it with,

    I did want to show you it cracking gmail but it only breaks 10 captcha's a day.
    Funny thing is there sign up for is not protected, so you could create a large amounts of accounts to rotate.

    There FAQ must be out dated as it works pretty well. It uploads the image as a base64 string to a webservice and then when it has cracked it alerts you and puts it in the clipboard.

    Seriously, this can read Google Captcha's - I wouldnt have thought that was possbile for standard OCR. Man, things must have improved recently. This could change the game!

    It gunzips the image and then uploads it to the server and is given a unique hash. It then polls the server waiting for the server to finish the OCRing and breaking of the captcha


    Eg 5 seconds left to crack the image

    And in 5 seconds the result will be returned back

    If any one wants my sniffer logs let me know as they are a bit big to post here but are quite interesting :)

    You can use wireshark but for pure http traffic you would be best off with a product called
    "IEInspector" you will need to get the standalone version so you can stuff any program rather than the intergrated IE version.

    Let me know if you need a key once you get it I will send you log file as it makes it so easy to view what's going on.

    There's a better solution than webvisum, try to google for captchamonster
    And you don't need any invitation to this
