If you open http://www.klaudette.com/galeria/captcha.php, you will see the errors. Apparently there was a bug in PHP documentation.

To remove those warnings -
Edit captcha.class.php and replace

Code Select Expand


$aCharDetails = imageftbbox($iFontSize, $iAngle, $sCurrentFont, $this->sCode[$i]);


with

Code Select Expand


$aCharDetails = imageftbbox($iFontSize, $iAngle, $sCurrentFont, $this->sCode[$i], array());


and replace

Code Select Expand


imagefttext($this->oImage, $iFontSize, $iAngle, $iX, $iY, $iTextColour, $sCurrentFont, $this->sCode[$i]);


with

Code Select Expand


imagefttext($this->oImage, $iFontSize, $iAngle, $iX, $iY, $iTextColour, $sCurrentFont, $this->sCode[$i], array());


That should do the trick.

I've been struggling with adding this MOD for a while now, since being told I can't use the plug-in version as my install is bridged with SMF.

The instructions at the head of this thread for installing this MOD seem incomplete. For example, the earliest instructions state:

Edit themes/yourtheme/theme.php

Add
Code:

'{CONFIRM}' => $lang_display_comments['confirm'],


just after
Code:

'{COMMENT}' => $lang_display_comments['comment'],


Add
Code:

<tr>
  <td class="tableb_compact" colspan="2">
    {CONFIRM}
  </td>
  <td class="tableb_compact" colspan="2">
    <input type="text" name="confirmCode" size="5" class="textinput"> <img src="captcha.php" align="middle">
  </td>
</tr>


just after
Code:

<!-- END input_box_no_smilies -->
                                </td>
                                <td class="tableb_compact">
                                <input type="hidden" name="event" value="comment" />
                                <input type="hidden" name="pid" value="{PIC_ID}" />
                                <input type="submit" class="comment_button" name="submit" value="{OK}" />
                                </td></tr>

Yet, when I look at my themes/yourtheme/theme.php file (based on the Classic theme), I see only this:

Code Select Expand

No

Code Select Expand

'{COMMENT}' => $lang_display_comments['comment'],
string that I can see, nor any

Code Select Expand

<!-- END input_box_no_smilies -->
                                </td>
                                <td class="tableb_compact">
                                <input type="hidden" name="event" value="comment" />
                                <input type="hidden" name="pid" value="{PIC_ID}" />
                                <input type="submit" class="comment_button" name="submit" value="{OK}" />
                                </td></tr>


There also appears to be a LOT of changes to the original instructions provided in this thread, yet the instructions at the head of the thread have not been updated to reflect those changes. In short, I don't see how to modify my install to use this MOD at this time. Thanks for your time...

Use the plugin version then.

@Nibbler
Sorry but she can't cause her gallery is bridged with SMF and plugin doesn't work with SMF and joomla bridge

@ComputerLady
If you can't find codes on your theme.php then you should copy them from themes/sample/theme.php
In your situation you should
- Copy & Paste $template_add_your_comment variable (starting by $template_add_your_comment = <<<EOT and ending by EOT;)
- Copy & paste theme_html_comments($pid) function

Hi,

I had earlier used Abbas' captcha codes to install this feature.
It worked very well.  Thank you guys !

I recently installed the Tagblitz plug-in.
I got an error - a box with a red cross in the place where the captcha code should appear.
See:  http://www.photograffs.com/displayimage.php?pos=-1509

can anybody help resolve this problem.
(I had earlier posted this problem under tagblitz topic.
I'm not trying to cross-post.  But I guess it is more appropriate under this topic).

I'm no good in php.
Anybody can help?

Thanks.

[Sami]

The problem is Tagblitz plug-in , it's injecting javascript to Captcha image and break it

can anybody help resolve this problem.

Actually you did cross-post
For now you can disable tagblitz and wait for it to solve the problem

[eka]

Thank you Sami.
I'll wait for the solution.

Hi I tried to install this mod because even with a code users had to type (taken from a static image) I was still getting spam. Theres so much code to add in alot of files for this mod its difficult for someone without alot of php knowledge, and in some files where it says 'Add........ After........' Somethimes the code doesnt exist.
I then downloaded the 'plugin' by Sami and it said about using plugin manager to install it. Where do I find this or is it something I have to install to my gallery?

[Abbas Ali]

Ask captcha plugin related questions in the respective plugin thread.

[eka]

Hi,

I used Abbas Captcha for my site by amending the codes (before the plugin version came out).
I then upgraded my cpg to 1.4.12.
The captcha feature disappeared but the comment box was left intact.

Would it cause any problem now if I load the captcha plugin now?
Do I need to delete some lines in the code... before uploading the plug? and if so what lines....

Pse advice.

[Abbas Ali]

After upgrade did you preserved db_input.php and theme files from your previous version? I mean while upgrading did you overwrote all previously modified files? If yes then you can apply the plugin straightaway. But if you had preserved the old modified files then the captcha mod code should be removed from them before installing the plugin.

[Jochus]

Is it possible to use Captcha for the reporting of pictures to the admin? Because I receive several SPAM mails a day.

I tried captcha and it works perfect in combination with my comments, but not for my reports ...

[Abbas Ali]

Yes it is possible to use captcha anywhere we are getting the user input. Please start a separate thread for this though as this thread deals with captcha for comments only.

[Jochus]

Okay, thnx

[Master of Orion]

Can you post the last version of Captcha

[scottcrew]

The latest version of CATPCHA is at:
http://forum.coppermine-gallery.net/index.php?topic=36319.0

HTH!

[Joachim Müller]

@ Master of Orion: stop cluttering this board by requesting "the most recent version" of mods. The most recent versions already exist in the mod threads. Don't be lazy, read the threads and you should be good. Mods don't need to get adapted to minor version updates (e.g. from cpg1.4.13 to cpg1.4.14), you just have to re-apply the mod after updating, that's all.
