ASP.NET application on IIS 6.0

[Steve]

I have a web application written in ASP.NET. It installs
and runs correctly on IIS 5.0 but when run under IIS 6.0
it fails to display images or load js files from
subdirectories (ie if the page has an image with
src="images/title.gif" then the image does not display.
I understand this is an issue with IIS 6.0 default
installation being 'locked down' but I cannot figure out
how to get the app to work correctly.
Any suggestions?
