First of all, thank you for sharing this nice piece of script which does everything which it is intended to do. While trying it out locally on my computer using XAMPP, i am facing a problem with language part.
I have created a language file in Hindi using IndicIME and for characters in it to show properly I created/typed in Notepad and saved as UTF-8 format. Now when I select this hindi.php from Language option at all the forms I do not see Captcha image for validation. Now, the irony is that I know the reason why this problem is there but I can not seem to find a way to solve it.
What I understand is that the reason of this problem is those extra characters saved in the header of hindi.php file when saved as UTF-8 instead of Ansi (default) format and because of these extra characters in file header the session is destroyed or already started before the Captcha class file is included, please correct me if I am wrong.
Again when I save hindi.php as Ansi format the Captcha image starts showing up BUT instead of proper asian language (hindi) characters I only see question marks (?) every where.
In FireFox the website is showing only with the Captcha image problem as mentioned above but in Internet Explorer 7 I am getting following error:
Warning: Cannot modify header information - headers already sent by (output started at xxxxxx\weblog\web\lang\hindi.php:1) in xxxxxx\weblog\web\admin\inc\functions.inc.php
With the above it is confirmed that the problem is due to saving of language file in ANSI format.
Please help me to sort out the problem as UTF-8 encoding in html files is a necessity to show Asian and other languages also I presume.
If you wish I can send you my hindi.php and if my problem is solved it would be great to see to become part of Weblog and may be very helpful for all the users who want to have their Weblog in hindi.
Thanks.

Thanks for the information. I do plan on removing the captcha from my scripts and adding this one:
http://www.phpcaptcha.org/
I`m not actually sure about the captcha problem to be honest, so I don`t think I can help. You might want to try using the above captcha instead as that can read from a word list.

Hi Admin,
In the past I had reported two problems: 1) Asian Language problem and 2) Captcha spacing problem
The problem reported here in this topic has got nothing to do with Captcha and is purely related to using UTF-8 characters in language file. Please do let me know if there is explanation required apart from what I had reported above earlier.
Thanks.

Sorry I didn`t get back to you again regarding this. Been to busy.

I am not sure whether or not it has got anything to do with the Hindi translation.
The captcha does not show on my English page, nor on my freshly translated Dutch page.
Where (I assume) the Captcha is to appear, ie. just below the text entry field, it just shows: "Enter Security Code", and the same equivalent in Dutch.
So, i assume there might be a fault with placing the image in the right place or somehing.
I use version 4.0.

Do you have the GD graphics library enabled on your server? Check that first. Without that the captcha`s will never load.
Offline
Yes, checked that via the phpinfo() command.
GD2 is enabled, Freetype, etc, it is all there.

Ok, just wondered. Possibly an issue with the captcha code then.
Offline
OK.
So, it might be best to disable Captcha for now then, other wise people can't post (or me, for that matter).
Offline
Ok, sorry about that.

I think I am the one who should apologise (or maybe my webhost).
This morning, everything was there as it should be.
(See my post in Maian Greetings, which explains a bit more about that).

Great news.

It seems I am also having trouble displaying the captcha code image when I select a different language as well. The english works fine though.

Hmm, not sure what would cause this. The language file shouldn`t cause any problems I wouldn`t have thought.

This is weird. The op is correct. If I convert back to ansi from utf-8, the captcha code image is viewable. However, the language pack file having special characters shows symbols, but is viewed fine over the browser.
David, I can resend you the file again or you can convert it to ansi before uploading it.
Offline
Yes, sure, that would be fine.
