I see no hidden input value/url value/session cookie/nothing. It means telepathy! Well take a look at www.php.net/gd for generating images also here http://pear.php.net/package/Numbers_Words . See this random number generating function http://www.php.net/mt_rand too :-) Too many links, nah ? :) Store the number in a session variable and check if both match or not (you can store the md5 value too in a Cookie).Hope that helps, -- Josip Dzolonga http://josip.dotgeek.org jdzolonga[at]gmail.com
