 'Declare a variable to contain the path 
 'of each selected item. Even though the path is aString, 
 'the variable must be a Variant because For Each...Next 
 'routines only work with Variants and Objects. 
 Dim vrtSelectedItem As Variant 

 'Use a With...End With block to reference the FileDialog object. 
 With fd 

 'Add a filter that includes GIF and JPEG images and make it the second item in the list. 
 .Filters.Add "Images", "*.gif; *.jpg; *.jpeg", 2 

 'Sets the initial file filter to number 2. 
 .FilterIndex = 2

 'If the user presses the button... 
 If .Show = -1 Then 

 'Step through each string in the FileDialogSelectedItems collection. 
 For Each vrtSelectedItem In .SelectedItems 

 'vrtSelectedItem is aString that contains the path of each selected item. 
 'You can use any file I/O functions that you want to work with this path.

 MsgBox "Selected item's path: " & vrtSelectedItem 

 Next vrtSelectedItem 
 'If the user presses Cancel...

 End If 
 End With 

 'Set the object variable to Nothing.
