[RESOLVED] How can i use a captcha on my page

[bharanidharanit]

Here's what I use, it's not very secure at all!

<%
     Dim strCaptcha, pChar, pCount
     pChar = "0123456789"
     pCount = Len(pChar) 
     Randomize
     For i = 1 To 5
     strNumber = Mid(pChar, 1 + Int(Rnd * pCount), 1 )
     strCaptcha = strCaptcha & strNumber
     response.write("<img src='images/numbers/" & strNumber & ".gif' />")
     Next
     session("captcha")=strCaptcha
%>

With your coding i am getting output like this.

How can i fix this?
