Odd place to post Netscape query

[R-D-C]

I know this may be an odd place to post a Netscape query but here goes
anyway.

Got a basic ASP.NET page that references JPGs from an 'images' sub-folder
using HTML img tag.

In IE, everything is fine, in NS7, the picture is not shown. If you browse
directly to the jpg file, the server returns:


You are not authorized to view this page
HTTP 401.3 - Access denied by ACL on resource
Internet Information Services


Any ideas?
