Assuming the images are formatted in-line and are located in the header & footer, respectively, following code should do the job for all documents in the selected folder — just add the paths & names for the images in the ‘FileName:=»»‘ variables.

Sub UpdateImages()
Application.ScreenUpdating = False
Dim strFolder As String, strFile As String, strDocNm As String, sWdth As Single
Dim wdDoc As Document, wdHdFt As HeaderFooter, wdRng As Range, wdIshp As InlineShape
strDocNm = ActiveDocument.FullName
strFolder = GetFolder: If strFolder = "" Then Exit Sub
strFile = Dir(strFolder & "*.doc", vbNormal)
While strFile <> ""
  If strFolder & "" & strFile <> strDocNm Then
    Set wdDoc = Documents.Open(FileName:=strFolder & "" & strFile, AddToRecentFiles:=False, Visible:=False)
    With wdDoc
      With .Sections(1)
        For Each wdHdFt In .Headers
          With wdHdFt
            If .Exists Then
              With .Range
                If .InlineShapes.Count > 0 Then
                  Set wdRng = .InlineShapes(1).Range
                  With .InlineShapes(1)
                    sWdth = .Width
                    .Delete
                  End With
                  Set wdIshp = .InlineShapes.AddPicture(Range:=wdRng, FileName:="")
                  With wdIshp
                    .LockAspectRatio = True
                    .Width = sWdth
                  End With
                End If
              End With
            End If
          End With
        Next
        For Each wdHdFt In .Footers
          With wdHdFt
            If .Exists Then
              With .Range
                If .InlineShapes.Count > 0 Then
                  Set wdRng = .InlineShapes(1).Range
                  With .InlineShapes(1)
                    sWdth = .Width
                    .Delete
                  End With
                  Set wdIshp = .InlineShapes.AddPicture(Range:=wdRng, FileName:="")
                  With wdIshp
                    .LockAspectRatio = True
                    .Width = sWdth
                  End With
                End If
              End With
            End If
          End With
        Next
      End With
      .Close SaveChanges:=True
    End With
  End If
  strFile = Dir()
Wend
Set wdDoc = Nothing
Application.ScreenUpdating = True
End Sub

Function GetFolder() As String
Dim oFolder As Object
GetFolder = ""
Set oFolder = CreateObject("Shell.Application").BrowseForFolder(0, "Choose a folder", 0)
If (Not oFolder Is Nothing) Then GetFolder = oFolder.Items.Item.Path
Set oFolder = Nothing
End Function

As you can see, even addressing header & footers is itself not straightforward (a Section can have three of each) and, as Cindy said, there is no VBA equivalent of the UI’s ‘Change picture’ button.
