My appologies if this was brought earlier.
my captcha implementation is working fine.
however i would like to know how to achieve this:
when a user submits the form , with the correct captcha code, it goes to page 2, on this page, i check the entered values and if there is an error, i hava a history.back(-1) link to the form to edit his form data..
now when he goes back using the link, the captcha image is the same one as the original captcha when he first filled the form, how can i make the image reload when he hits the link above?
i tried <body OnLoad="reloadCAPTCHA()" > but its not working.
any ideas?

The file is set not to cache which in most cases IE works with, but with Firefox it doesn't. I have tried many ways but have not found a solution either.

I had the same problem. As a workaround, I added OnFocus="javascript:reloadCAPTCHA();" to the text box in CAPTCHA_form_inc.asp. That way, the image changes each time they tab to or click on the code field.
