ASP Server.Mappath

[Y2K]

I have a thumbnail viewer which displays images on a webpage.
Currently, the images reside in a subfolder of the root, and this works
fine. I understand the main problem here is my limited knowlege of
ASP.

Here's the current setup:
c:\testproj\imageviewer = Virtual directory named "IMGviewer"
c:\testproj\imageview\upload\pics = folder that contains images

The following code works:
ImageConn = "pics/"
Set fso = CreateObject("Scripting.FileSystemObject")
'Set fattributes = fso.GetFolder(server.mappath(""&ImageConn&""))

The problem is, the images are in another folder:
c:\testfolder\myimages\pics_5

I've tried the following, and get a "path not found" error.
Set fattributes = fso.GetFolder("c:\testfolder\myimages\pics_5\")
Set fattributes = fso.GetFolder("c:\testfolder\myimages\pics_5")
Set fattributes =
fso.GetFolder("//servername/c$/testfolder/myimages/pics_5")
Set fattributes =
fso.GetFolder("//servername/c$/testfolder/myimages/pics_5/")

Can anyone tell me what I'm doing wrong? Thanks.
