You need to tell Word what to set the position relative to. Try something based on:
Code:
Sub ImageInHeaderFooter()
Application.ScreenUpdating = False
Dim Shp As Shape
With ActiveDocument.Sections(1)
Set Shp = .Headers(wdHeaderFooterPrimary).Shapes.AddPicture( _
FileName:="\\URL2Image.jpg", SaveWithDocument:=True)
With Shp
.LockAnchor = True
.LockAspectRatio = True
.RelativeHorizontalPosition = wdRelativeHorizontalPositionPage
.RelativeVerticalPosition = wdRelativeVerticalPositionPage
.Left = CentimetersToPoints(-0.5)
.Top = CentimetersToPoints(0.7)
.Width = CentimetersToPoints(8.2)
End With
Set Shp = .Footers(wdHeaderFooterPrimary).Shapes.AddPicture( _
FileName:="\\URL2Image.jpg", SaveWithDocument:=True)
With Shp
.LockAnchor = True
.LockAspectRatio = True
.RelativeHorizontalPosition = wdRelativeHorizontalPositionPage
.RelativeVerticalPosition = wdRelativeVerticalPositionPage
.Left = CentimetersToPoints(-2.8)
.Top = CentimetersToPoints(25.6)
.Width = CentimetersToPoints(21.8)
End With
End With
Application.ScreenUpdating = True
End Sub
Presumably, you'll need to adjust the .Left values. Note that I've omitted the .Height specifications. Assuming your images already have the correct aspect ratio, locking it before resizing either the .Height or .Width is sufficient.
