Not bad...even looks like it would work for semi-color blind people(not sure how well it would work for sure though)

It is a little hard to read though. :P

Did I kill another thread? :P

I am just about finished with my Captcha for my Anti-Spam ACP mod...personally I think it would work great against spam bots, and best of all it is usually very easy to read. ;)

That appears to be your undoing, as it wouldn't take too long to get some code to locate those letters, and pass the letter locations to an OCR (they are better these days than you think). You should add some form of distortion or noise, else it'll be trivial to break them.

It may be. :P

I can always add more fonts(just have to drop them in the fonts/ folder. :mrgreen:
(well, to tell you the truth, I don't know how to add distortion or noise, this was a captcha mod for phpBB2 that I changed around to fit my needs, and I never did any GD work. :()

If you know of a good tutorial(online) on doing that kind of stuff that would be awesome. 8)

In My Internet Official Group Test forum of Phpbb3.0OlympusBeta4 CVS I have received of many complaints from my official UserGroup of the unreadability of many if not the majority of Capture images.

This should be addressed as it gives severe affection to my new UserGroup patrons.

No, it was Berlusconi, on the 7th day.

My other Official Posting apears to have been victimised by deletion.

On my Official CVS Test Board, my UserGroups complain of this over-complicated and under-neccesary registration process known as Captcha. Surely there is a more simplistic and user-pleasuring alternation.

Yes, it is "print the agreement, sign it and fax it along with your ID card to the admin".
