If UCase(Right(ext, 3)) = "TIF" Then
Response.ContentType = "Image/tiff"
Else
Response.ContentType = "Application/pdf"
End If

If forceDownload Then
Response.AppendHeader("content-disposition", "attachment;
filename=" & name)
Else
Response.AppendHeader("content-disposition", "inline;
filename=" & name)
End If
'
Response.Write(System.Security.Principal.WindowsIdentity.GetCurrent().Name())

Dim MyFileStream As FileStream
Dim FileSize As Long

MyFileStream = New FileStream(fname, FileMode.Open)
FileSize = MyFileStream.Length

Dim Buffer(CInt(FileSize)) As Byte
MyFileStream.Read(Buffer, 0, CInt(FileSize))
MyFileStream.Close()
Response.BinaryWrite(Buffer)

Did you verify that the tiff is associated with any viewer? Is there a
possibility that the tiff header is getting lost or corrupted in either the
download or the viewing? In my experience, while tiff files are fairly easy
to work with, they are also fairly easy to mess up as well.
