i see all the questions on my page but i cant see image which is generating the code

 

Can you post the URL of the website where you got the captcha script?

 

there you are:

deleted link -that is not a proper address to the spot you got it from - your friendly mod Ishkey

 

The captcha.php source code is needed to find out why you’re having problem generating the image. If the code is small you may post it here or give us a link where it can be downloaded.

Also check to make sure captcha.php is at the same location of your form.

 

The link you PM is just a site where the captcha.php script was used. It does not allow me to download it.

Just to be cleared about your problem – do you have a copy of captcha.php?

If not, you can get one from a list of websites that offer free Captcha Scripts here:
