IIS ASP Write permissions

Hi

This is what I'm trying to do. From an ASP.NET script (using XP, IIS), I want to create and write to a file in the local directory. The script is http://localhost/images/asptest.aspx and I want to write to a file located in the images directory, next to the aspx file. What permissions should I set under IIS? I tried to give write permissions to the images folder but no luck, the exception that I'm getting is "System.Exception: System.UnauthorizedAccessException: Access to the path c:\inetpub\wwwroot\images\1.jpg is denied. at System.IO.__Error.WinIOError(Int32 errorCode, String str) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share, Int32 bufferSize, Boolean useAsync, String msgPath, Boolean bFromProxy) at System.IO.FileStream..ctor(String path, FileMode mode, FileAccess access, FileShare share) at System.IO.File.OpenWrite(String path)..."

I would appreciate your help on this one, I know it must be something simple..

I don't know with NET. Most IIS servers operate as the IUSR_computername user when handling anonymous web surfers, or the logged-on user account if your users authenticate.

Try the NET forum if no one jumps in here.
