    Disable Automated Signup...

    Hi *!
    I have for my website a form to sign-up for some service. Now, in order to disable automated sign-up I want to display some image (that displays some text) and the user types-in that text manually to be able to sign-up successfully. I am not sure what it is called , tried googling for "disable sign-up image" and some variants of it, but the results were not too much of help.

    I am using php5 on my website.

    Any comments/suggestions are highly appreciated,

    Thanks in Advance,
    Regards,
    Usman.

    PHP Image Verification is the term for which you are looking.

    What you search is a CAPTCHA ("Completely Automated Public Turing test to tell Computers and Humans Apart")
    http://en.wikipedia.org/wiki/CAPTCHA

    Here are some examples on how to realize a captcha with php
