Problem with Security Images (Lite)

Hey, I'm having problems getting the login Security Number images to work. I don't know whats up with them, I tried looking at the security_image.asp file but couldn't really see much as I no good with ASP. Heres the code from the security_images.asp, (with the initital Terms and Condition code removed for ease of readin here)

"<% @ Language=VBScript %>
<% Option Explicit %>
<%

'Set the buffer to true
Response.Buffer = True

'Declare variables
Dim objADOStream           'Holds the stream object
Dim intImageNumber       &nbs p;  'Holds which image number to show
Dim strImagePath           'Holds the image path and image name

'Initiliase variables
strImagePath = "security_images/"


'Get the image number
intImageNumber = CInt(Request.QueryString("I"))

'Get the image security code number to display
intImageNumber = Mid(Session("lngSecurityCode"), intImageNumber, 1)
     
'Get the path and the image to show
strImagePath = Server.MapPath(strImagePath & intImageNumber & ".gif")
    


'Set the stream object
Set objADOStream = server.createobject("ADODB.Stream")

'Open the streem oject
objADOStream.Open

'Set the stream object type to binary
objADOStream.Type = 1

'Load in the image gif
objADOStream.LoadFromFile strImagePath



'Set the right response content type for the image
Response.ContentType = "image/gif"

'Display image
Response.BinaryWrite objADOStream.Read

'Flush the response object
Response.Flush


'Clean up
objADOStream.Close
Set objADOStream=Nothing

I thought I may be able to disable the need for a Security Code when registering from the Admin menu, but I couldn't find anything.

Thanks in advance!

You may be able to generate numeric charaters as opposed to images for that matter, this is also a suggestion to Borg to suplly an option for this, the only problem would be, the main point of using images is to avoid automated registrations, so bots can't read the images, but I guess this sort of thing is not seen much now a days, I guess.
