I did see other threads concerning this but none with a solution.
Hopefully I'm including all the info you need I am answering the questions you asked in this thread and what more I can think of: http://www.jxdevelopment.com/component/option,com_fireboard/Itemid,68/func,view/id,4767/catid,14/

It's very hard to give a definitive answer without any more information. There could be about a million things that can go wrong.

Are you running PHP with Safe Mode? That could screw things up. Are the permissions on the files and the directory correct? If you type the url for the images directly, do they show up in the browser? Do you get an error message? Did you get an error message when you installed Jambook?

MySQL is version 4.1.22
PHP is version 5.2.5
Joomla version 1.5.0
Php is not running with safe mode.
The permissions for the files that are installed seem to be ok. I have to chmod the configuration file to 766 but that is the only permissions changed. All the other permissions are appropriate for Joomla.
When I type the url for the images it comes up with "oops url must be broken" type of error.
I checked the folder contents inside the /components/com_jambook/captcha folder and it is completely empty with the exception of the default index.html page.
I also made sure that system legacy plugin was activated before install.
Oh and at no time during installation did I get any errors and when I access the jambook page there are no errors generated.

I would really like to keep the jambook component instead of finding a different one. Mostly because if this one works it is much more configurable than any others I've looked at so far.

As a side note I also had an issue with the configuration tabs being empty after installation. It wasn't retrieving the information from the configuration file. I noticed in one of the threads concerning this you posted a link to a different version which fixed that but you don't have that file as a download on your list of files? I thankfully found that link and downloaded the file com_jambook_1_0_RC1b.zip and it works fine.

thanks a bunch for your good work,
