Customising the customer portal

Customising the customer portal


Hi
 
Am I doing something wrong here - I'm using build 7512 (evaluation license) and have completed the customer portal settings to upload images and change font colours.
 
It works fine on this page /sd/SolutionsHome.sd where the background colour in the heading is as I want it but on other pages e.g. /HomePage.do the header seems to be pulling in a background image /images/scp-header-bg.gif so therefore is not showing the colour selected in the configuration.  Problem is our logo looks awful on that background (see attachments).
 
Is there another skinning/theming option somewhere to remove this or are we going to have to dive into changing CSS and images (and keep having to update this when we upgrade?
 
Thanks
