captcha image not displayed (guestbook version 3.0.3)

Running joomla version 3.4.1 with guestbook component 3.0.2 installed no captcha images are displayed on front end. Instead "captcha afbeelding" (most likely in English this will be displayed as captcha picture).
This exact same issue was already discussed in the following forum thread: viewtopic.php?f=2&t=12123&start=10
But since it discussed a old version of phoca guestbook I started a new item.

Only reCaptcha or joomla default(when captcha-reCaptcha plugin is configured)are displayed correctly.

I checked for GD support in my phpinfo and it shows as installed.
To me it looks like the image location is wrong as inspect gave me the following source location: "/joomla25plus/index.php?option=com_phocaguestbook&view=guestbooki&id=3&Itemid=132&phocasid=368d59b80233a06f635401d8e81c157e"

The previously referred topic mentioned a setting Jhtml and Jroute, but I was unable to locate the setting.

Any guide to fix this is highly appreciated since it is holding me back from publishing the guestbook.

No clue on what the phocasid stands for but to me the link looks like it is pointing to the guestbook component where it should be pointing to an image.

Hi, the link is a link to page which only generates the captcha, sid is here to prevent from caching the image (in case of reload, new image is forced)

Does't any method work for you?

None of the link methods is working for multiple captchas(standard, math, ttf, easycalc). The only setup that pictures a working captcha with image, is one of the reCaptcha options(joomla default/recaptcha system plugin or the components recaptcha).

Hmmm, this can mean some problem on the server as the images are rendered by php - GD library by these methods - so maybe some permissions or ownership problem when creating the image, or problem when creating the image by GD library, etc. :idea:

Maybe you're logged in at the front-end?

set the Enable - Captha Users to ALL and try again

then it is showed also for registered people

Is this perhaps the same problem as in my thread (viewtopic.php?f=2&t=28562).

Recaptcha gives an error message. Joomla standard seems to work. All other methods do not show the captcha image.

Am now using Joomla 3.4.1

Hi guys sorry for staying away for so long.
@ Jan could you elaborate on methods to trace down which of your suggestions might be the issue. How could I check for the server permissions for example?

@ jeejeestudio
Thanks for your suggestions. I tried both logged-in/logged-out. Didn't make any difference. Checked the applicability setting in the guestbook component, which was already set to all.

@Huber, not shure if this is a similar issue. It seems you get errors display. I just don't get an image(only the alt text).

I updated as well to Joomla version 3.4.1. No issues experienced yet.

Nevertheless, updating to Joomla 3.4.1 didn't solve the issue with the captcha images.

Kind regards
