Add an Image to Word Document and Scale it using VBA

how do i programatically add an image using VBA to a word document.

I've tried adding a bookmark to the word document and tried adding the image, but it always adds to the top of the form rather than the bookmark area. Should i persevere with the bookmark or is there another way to add the image?

See my code below:

Dim wrdApp As Word.Application
Dim wrdDoc As Word.Document
Set wrdApp = CreateObject("Word.Application")

Dim objWdRange As Word.Range
Dim GraphImage As String
Dim shortString As String 

shortString = Range("short").Value

GraphImage = "http://xxx.xxxxx.com/xxx/xxx.png?instrument=Image.png"

wrdApp.Visible = True
Set wrdDoc = wrdApp.Documents.Open("C:\Program Files\My Dropbox\dailystrategy.doc")

Set objWdRange = wrdDoc.Content

With wrdDoc


    If wrdDoc.Bookmarks.Exists("shortString ") Then
        wrdDoc.Bookmarks("shortString ").Range.Text = shortString 
    End If      

     If wrdDoc.Bookmarks.Exists("GraphImage") Then
        wrdDoc.Bookmarks("GraphImage").Range.InlineShapes.AddPicture Filename:=GraphImage, LinkToFile:=False, SaveWithDocument:=True
     End If


    wrdDoc.SaveAs "c:\temp\test.doc"

  ' close the document
    Set wrdDoc = Nothing
    Set wrdApp = Nothing
End With
