Image paths are incorrect, how do I fix?

I am re-building this website for a client, it is near finished, except for the facts that certain images wont display.

When I right-click the page, where the image should be, it says 'view image info', then tells me image not found, so it does exist, but I know its missing a crucial directory name. For instance, this is the non working path:



And the working path:



If I manually add mydirectory to the URL it shows the image.

How do I go about manually addding this directory name? I tried via my Manager, but I am unable to locate the code displaying it. If somebody would be happy to team view me to resolve this, you would be doing me a massive favor.

Thanks in advance.

I noticed my:

MODX_BASE_PATH
MODX_BASE_URL
MODX_MANAGER_URL
MODX_MANAGER_PATH
MODX_SITE_URL

details are incorrect, my manager, reports, system info displayed this.

Which file so I change this in? I need to remove previously default settings.
