[ic] No pictures in admin

[wbetzjr]

Hello:

New install, 5.3.2, on Linux. Installed as root, using user interch.
Interchange installed in default directory : /usr/local/interchange
Standard catalog demo works fine, shows pictures fine.

However, when clicking on "admin", although the page loads, there are no 
colors and no pictures, and the layout looks screwy.

Any ideas where the problem might be?
Where are the picture / css files for admin? (Or where SHOULD they be?)

Thanks,

Bill
