Orca icons missin - bad path?

Hello,

Orca's installed and the groups and forums set up, but the icons don't appear.  If I right click on any the path is http://www.mydomain.co.uk/orca/forum.gif for example, so I tried upload all the icons to the Orca subdirectory but that didn't work either.

It icons are already in this directory ../orca/layout/base/img so I'm guessing that there's a path error somewhere.

Does anyone know where this path might be?

Thanks.

OK, let me put it another way.

How do I change this:

http://www.blahblah.com/orca/button_l.gif

to this:

http://www.blablah.com/orca/layout/base_en/img/button_l.gif
