How to give permission to folders?

  I'm trying to get an image from my disk. I was using the following code:
  
              Dim img As New BitmapImage(New Uri(fileName, UriKind.Absolute))
              book.Imagen.Source = img
  
  fileName is a variable that contains something like: "E:/images//test.jpg"
  (after a long headache, I found that "/t" means tab, so I have to use "//t"... I din't knew this for VB but for other languages)
  
  Well, with an existing file, and a right string for it's name, this piece of code is telling me that the file doesn't exist:
  
  >>......If System.IO.File.Exists(fileName) Then
  >>.........Dim img As New BitmapImage(New Uri(fileName, UriKind.Absolute))
  >>......End If
  
  Just to be sure, I added some code to check wt...:
  
          Dim myOpenFile As New OpenFileDialog
          myOpenFile.ShowDialog()
          Dim fileName As String
          fileName = myOpenFile.FileName
  
  HAHA -I said-, now VB.NET can't tell me that the file doesn't exists
  Then I found that NET don't have permission to access that file and I get this exception: "System.Security.Permissions.FileIOPermission"
  
  (In other words, the compiler could tell me that I don't have permission since the begining and don't force me to add code to guess what is happening. I knew the file was there). Something that I am not used to is the NET security model... How should I work on this?
  
  Cheers,
