other cpatcha graphics ?

I have a working validation check (captcha) see the standard graphics for it in guestbook entry form.

Now my Q is; I've seen some graphics with a squared raster behind it and the numbers are randomly tilted (this to prevent recognition of spambots) how can I get that too ?

It's built into 2.4.1

I know it's built in 2.4.1 and it is working for me but what I like is a beter graphic display which prevents spambots from detecting it.

Ex; A graphic that is garbaged or has a background picture which confuses the newer spambots from detecting the graphiccode.

Most spamming is actually done using scripts and not programs and just sends the data automatically without ever visiting the page. I keep a log of all posts made to my own guestbook, successful or not, so I can see exactly what data was sent in the post. It has provided me with some useful information on how to improve my mousetrap.
Anyway the CAPTCHA I wrote for Lazarus is different from the one in AG so have a look at that. I also threw together a really simple one as can be seen at www.carbonize.co.uk/captcha.php

The problem with CAPTCHA is, and always will be, obscuring it enough to fool bots whilst keeping it legible enough for humans. I have some ideas on this and will be toying with them but until the spammers do start making automated scripts that can read my CAPTCHA I'm not going to worry about it. Any spam I get now I know has been manually entered.

If you want to see my data from the guestbook entries PM me and I will send you the link but I would rather it stayed private.

Thanks, thats what I mean, this captcha is in anyway more obscured then the standard one for AG, but it does not work in AG, any ideas on how to get it working ?

Will install Lazarus as soon as I can find time this week or so to see what it can do for me

I updated to lazarus rightaway to make it work better and faster for me, however.

Now the verification picture does not work, hmm, any ideas ?

Well we both know you have GD installed on your server so it's not that. When you say it's not working what do you mean exactly? Image not showing at all or showing but no characters?

broken image picture shows but no image

could it be active perl version 5.8.8 ?

Should hope not as Lazarus and Advanced Guestbook aer both written in PHP. Whats the link to your guestbook. PM it to me if you wish.

Well, I wouldn't be so shure as I just checked out and cannot remember installing that on my server.

Looked for that but can not find a windows distro for that and for that sake not one for the freetype library I need to, so I guess that's what's the problem here, I am a titsybitsy kinda dumb ass if it comes to that

Any chance you are willing to help me with that ?

I personally use XAMPP for my WAMP setup (Windows, Apache, MySQL and PHP). The full version comes with Perl but I use the lite version. Both do come with GD compiled and I'm sure that from around PHP 4 GD was included with PHP. I think you may have to enable it in php.ini.

Yes, right on the dot you were.

GD2.dll support was not enabled in php.ini file ( did a reinstall this afternoon and I guess the ini file was replaced too, explaining why gd support did work on AG I guess )

Thanks for your quick reply and help.
