So, this may seem simple, but for an hour I wrestled with displaying images on IIS7 with vista. ASP.NET worked fine, but no static files, css, jpg's, gif's or anything. Just unformatted text.
Turns out when I added the web server in vista, I forgot to check the Static Content checkbox under World Wide Web Services / Common Http Features.
Hope this finds you if you are having the same problem.
