I had edited something inside captcha.php as I read on

require ( 'include / init.inc.php');

leave it to the back-to-date te 1.4.25 to now it works

I see the Captcha tool on the login and the register page.
I don't see the Captcha tool by the comment box

Then read the readme and perform the needed edits

I can't see the captcha image on the registration page, so when people try to register they got the error "confirmation code didnt match". I followed the intructions of this post http://forum.coppermine-gallery.net/index.php/topic,36319.msg225008.html#msg225008 but nothing happened. 
Link of my gallery: http://www.melinda-clarke.org/gallery/.
Thanks.

The first thing you need to do is upgrade. Your Coppermine version is out of date and vulnerable.
If you allow people to register with this old release then you will allow your site to be compromised.
(It is still vulnerable without new users too)

<!--Coppermine Photo Gallery 1.4.18 (stable)-->

After you upgrade you will need to "fix" your theme.

As you can see......
The captcha displays fine on this page: http://www.melinda-clarke.org/gallery/register.php?theme=classic

Thanks for the reminder!  I just upgraded my gallery.

Well I will try to fix the theme, because since the upgrade the captcha image is not the only thing that does not work  .
Thanks again.

SOLVED

I had big problems with this plug-in before getting it to work.

So hopefully I can help others by telling what I did:

1. Problem was that the image and text didn't show up at the registration page at all - solved by this post http://forum.coppermine-gallery.net/index.php/topic,36319.msg225008.html#msg225008

2. Problem was that image didn't show. Only a red cross. In the time I was searching for a solution my login timed out. So now I couldn't even log in again, because I couldn't see image. In the future maybe login confirmation should be disabled by default when installing.

3. Tried to delete the SQL table as mentioned in this post http://forum.coppermine-gallery.net/index.php/topic,36319.msg170592.html#msg170592 - now I could log in again.

4. Changed the settings in file codebase.php so that this problem wouldn't occur again.

Code:

    $CAPTCHA_DISABLE = array('login' => 'Administrators,Registered,Anonymous',´
        'register' => 'Administrators,Registered,Anonymous',
        'comment' => 'Administrators,Registered,Anonymous',
        'report' => 'Administrators',
        'ecard' => 'Administrators',
        );

5. I tried Installing and Uninstalling the plug-in several times - no luck.

6. Found that you can put the code to a file instead of a picture.
Find this in captcha.class.php

Code:

      function Create($sFilename = '') {

Change to

Code:

      function Create($sFilename = 'test.jpg') {

This way i could check that the everything worked, because the code was actually made in the jpg file. Hmmmm OK thats one step further.
NOTE: File can be found in the root folder and the picture will NOT show until you remove this 'test.jpg' again. Only one is allowed at the same time - file OR picture.
I have no idea why this was working with the file, but not with the picture on the page itself. Maybe someone can answer this?

7. Looked through this huge thread trying to find a solution - at the moment it's 40 pages big. Found this post from Nibbler

2) Clean the output buffer just before the image is displayed.
captcha.php
Find:

Code:

$code = $oPhpCaptcha->Create();

Change to

Code:

ob_end_clean();
$code = $oPhpCaptcha->Create();

8. SUCCESS - now everything worked and now I just changed the configuration in codebase.php to the settings I would like to have on my page.

9. Attached is also the Danish translation of the confirmation messages - Huge job to translate 

Hope that this is helpful to someone. I found this solution by searching the board!
