Captcha Help (Image broken)

Shizzell · February 20, 2008

Alright I'm trying to impliment this captcha:

http://dirpg.co.nr/ecaptcha.zip

and I get this when trying to impliment it:

http://dirpg.co.nr/page.php

I'm seriuosly out in the dark right now.

Am I missing a apache module that I need?

I say this because I tried implimenting a different captcha, and I get:

http://dirpg.co.nr/captcha/form.php

(A broken link to the image)

Thanks a lot,

Jake

Page.php looks like your session_start(); could be under some code. It must be at the top. Post some code!

And your Captcha images for me are linking to c:\www\ check your locations to the linking of them.
