verification images

installed the guestbook verification and gone through all the edits more than twice but still not getting any images showing

http://www.djdeano.cydelia.co.uk/guestbook/addentry.php

looked through the forum for answers but no one has come up with a solution

I have also uploaded all files again to make sure its not a folder issue

Thanks for any support on this

Got all the path settings in there correctly?
Any errors?
Does the guestbook work other than the image/s not showing?

A link would be appreciated.

everything works but can not process without the images for the verification

You're the second person with this problem. What version of PHP, Apache and MySQL are you running?

Hi

details are
PHP version 4.3.9
MySQL version 4.0.22-standard
Apache version 1.3.33 (Unix)

Everything looks fine. I would recommend getting your PHP updated as 4.3.10 was released to fix some major security holes. I wil look more into this problem. I wonder if it's not a GD problem.

ok
thanks Carbonize

i dont know whether i can get updated as i am with a company which they update when they need to but i will ask them

As suspected GD is not compiled on your system. GD is how PHP creates graphics and is used by all image verification scripts hence it not working.

ok
but i'm just a little confused
what is GD and how do i get it working please

thanks again

It usually comes with PHP, you must of chose not to compile it.

I have an idea I'm toying with. A simple anti automated posting technique that should work well. For a while anyway. It uses the same random characters as the image verification but is invisible so it will not affct normal posters in anyway but should stop automated postings. This method should work fine for you as it doesn't need to create an image.

Carbonize - here's my dumb question for the day concerning verification and spam posting bots - When the bots spam, are they actually "on your site" when they are posting? Could a person put a feature that forces the person to post from the page and not from a remote location?

Maybe something like

Just wondering if that would do it?

Ooops - sorry, that was my post just now -

There is no way of forcing a person to be on the actual page other than requring some randomly generated information from that page to be sent with the other data. If you look at the url bar for this forum it looks like http://proxy2.de/forum/posting.php?t=4167 This is an example of GET data. GET data is sent in the url request whilst POST data is not but is similar in format. The t in our URL represents thread and the number is the number of this thread. This is how data posting works. The guestbook works in the same way and all the spammers do is send the data they want posted straight to the addentry.php page as if it had been submitted normally.

Thanks - like I said, it was my dumb question for the day - I put a similar function into my mailform and it works like a charm - stopped all the craziness and I haven't had any spam for over a year....
