Images from roller themes 404 not found

Hi,

I have just installed JRoller 3.1 on Tomcat 6.0.13, Sun JRE
1.6.0_01-b06, Windows XP, MySQL 5.0.   I am able to log into roller,
create an account, a blog, post some entries, browse my blog, etc... The
problem I'm having is that no matter which theme I choose for my blog,
none of the images are displayed.  When I view the source of my blog, I
see image URLs such as:

http://localhost:8080/roller/rdelaplante/resource/images/metalLine.gif

When I try to directly access the above URL, I get roller's custom 404
not found screen.  I noticed that when I use the File Uploads screen,
the links to the files also begin with .../rdelaplante/resource/.   When
I click on a file that I previously uploaded, it takes me to the
following URL and the file is displayed:

http://localhost:8080/roller/rdelaplante/resource/README.txt



I cannot figure out why /resource/images/* fails. Can anyone please help me?


Thanks,
Ryan
