Inserting and resizing user defined images

Greetings all,

I am trying to have a user select a picture and input it into a range. I have come across the following problems. 1.) The aspect ratio stays the same and I want it to stretch the range. 2.) not all pictures are imported. You go through the process and nothing happens. (they are in the correct format). What am I missing here? I'm new at this so forgive me if its obvious.
The code is as follows:

Code:

---

sub InsertPictureInRange1()
    Dim picToOpen As String
    picToOpen = Application _
                .GetOpenFilename("Image Files (*.jpg), *.jpg, (*.png), *.png")
    If picToOpen <> "" Then InsertPictureInRange picToOpen, _
                        Range("d59:f68")
End Sub

Sub InsertPictureInRange(PictureFileName As String, TargetCells As Range)
    ' inserts a picture and resizes it to fit the TargetCells range
    Dim p As Object, t As Double, l As Double, w As Double, h As Double
    If TypeName(ActiveSheet) <> "Worksheet" Then Exit Sub
    If Dir(PictureFileName) = "" Then Exit Sub
    ' import picture
    Set p = ActiveSheet.Pictures.Insert(PictureFileName)
    ' determine positions
    With TargetCells
        t = Cells(58, .Columns.Count).Top
        l = Cells(.Rows.Count, .Columns.Count).Left
        w = .Offset(0, .Columns.Count).Left - .Left
        h = .Offset(.Rows.Count, 0).Top - .Top
    End With
    ' position picture
    With p
        .Top = t
        .Left = l
        .Width = w
        .Height = h
    End With
   
    Set p = Nothing
End Sub

This is in excel 2007 by the way. Sorry I forgot to put it in the title.
