TOPIC: Security Image

Hi,
I have just installed JoomlaComment on my test site.. www.dev.worldbznews.com and can not see the security image. Any idea? Thanks in advance.

Hi Choudhury,

I think you do not have GD library installed on the server,

You can check if GD is enabled or not by by putting a php file with phpinfo() and then call it from browser.

Basically you should see following in GD section:

GD Support enabled
GD Version bundled (2.0.34 compatible)
FreeType Support enabled
FreeType Linkage with freetype
FreeType Version 2.1.4
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled
XBM Support enabled

Cheers,

There is also an easier way to check if GD is enabled. Log in your joomla administration, go to help -> system info and there you can look for GD library.
Either it is the GD library not installed or it is file permission issue(I think)

Thank you for your reply guys. I believe my GD is installed already. Below is the info...However I am using PHP 5.2.5
==============
GD Support enabled
GD Version bundled (2.0.34 compatible)
FreeType Support enabled
FreeType Linkage with freetype
FreeType Version 2.1.9

PNG Support enabled
WBMP Support enabled
XPM Support enabled

Here is my core configuration in case yo want to know...

I have the same problem, all the above are enabled in the php, I am using joomla 1.5, I cannot see the security image, thanks in advance

Same problem here, does anyone have an answer? If you can take a look at this page I would appreciate it.

QuicksSilver Templates

You too, are getting Server Internal Error:
http://quickssilver.com/components/com_comment/joscomment/captcha.php?refid=ffd09b4bb79c684661fd37b3294edfae

Please look at your error log for more info.

One of the reasons why captcha is not working are file permissions.
Check the file permission of captcha.php and if different than 644, change it to 644.

Hi,
yesterday I installed Jomla! Comments and today gd support. But I have the same problem - I can't see the image.

From error log:

[Thu Aug 07 09:56:29 2008] [error] [client 176.16.0.2] PHP Warning: imagepng(): supplied argument is not a valid Image resource in /srv/www/htdocs/Joomla/components/com_comment/joscomment/captcha.php on line 70, referer: intranet.plbohnice.cz/index.php?option=c...view&id=91&Itemid=93

I think I need have installed support for something more ?

Thanx

Which version of GD did you install.
On line 70 is the imagepng function: de2.php.net/imagepng

Hinweis: ACHTUNG: Die PNG-Unterstützung ersetzt die GIF-Funktionen ab der GD-Bibliothek Version 1.6. Diese Funktion ist also nur verfügbar, wenn Sie eine Version ab 1.6 verwenden.

From phpinfo:

GD Support enabled
GD Version bundled (2.0.28 compatible)
FreeType Support enabled
FreeType Linkage with freetype
FreeType Version 2.1.10
GIF Read Support enabled
GIF Create Support enabled
JPG Support enabled
PNG Support enabled
WBMP Support enabled
XPM Support enabled
XBM Support enabled
JIS-mapped Japanese Font Support enabled

Would you check the following with Filezilla.

go to /srv/www/htdocs/Joomla/components/com_comment/joscomment/captcha and look for the png pictures. Do you see them there?

Did you make any changes to captcha.php?

I found that there is a module for Apache2 named mod-captcha.
I am a little afraid of installing to production server, so I ask first: Can this be the right way to make it work?

No, I did no changes and yes, the pictures are there

I have been lurking hoping that your reponse to this would solve my problem. I have renabled the the captcha function at my site. www.fungreenfair.com . I have not changed the
I am wondering if I could install a second version of the

Hi guys, I'm having the same issue. Here are some info:

- The Security image isn't showing;
- The captcha.php file is set as 644;
- I got the bg1.png to bg3.png files into the Captcha folder;
- The GD is enabled and its version is bundled (2.0.34 compatible);
- Joomla version is 1.5.8;
- The installed JoomlaComment version is 3.26;
- PHP version is 5.2.8;
- MySQL Client API version is 5.0.77;
- No error message shows in my site, just the Security Image doesn't show up;

Any idea how to fix it?

Thanks in advance.

right click on the image ->properties and then copy the path. Paste in the url and check if the image is generating internal server error message.

Hi Daniel, good morning.

Yup, here is the error message:

Just to let you know the joscomment and captcha folders are set as 755 attributes.

and what does the error log say?
