Why doesn't SaveAs use correct PixelsPerInch in macro?

I have a macro which converts Word docs to htm. The problem is that the images are always saved as 96 ppi, even though I have specified 240 ppi.

Any ideas on how to fix?

Here is my macro:

Sub Doc2htm()
     With ActiveDocument.WebOptions
        .RelyOnCSS = True
        .OptimizeForBrowser = False
        .OrganizeInFolder = True
        .UseLongFileNames = True
        .RelyOnVML = False
        .AllowPNG = True
        .ScreenSize = msoScreenSize800x600
        .PixelsPerInch = 240
        .Encoding = msoEncodingWestern
    End With

        .UpdateLinksOnSave = True
        .CheckIfOfficeIsHTMLEditor = False
        .CheckIfWordIsDefaultHTMLEditor = False
        .AlwaysSaveInDefaultEncoding = False
        .SaveNewWebPagesAsWebArchives = True
    End With

    Dim newName As String
    Dim fileDir As String
    newName = ActiveDocument.Name
    If InStr(newName, ".doc") = 0 Then Exit Sub
    newName = Left(newName, InStr(newName, ".doc") - 1) & ".htm"
    fileDir = Left(ActiveDocument.FullName, InStrRev(ActiveDocument.FullName, "\"))

    ChangeFileOpenDirectory fileDir
    ActiveDocument.SaveAs FileName:=fileDir & newName, FileFormat:= _
        wdFormatFilteredHTML, LockComments:=False, Password:="", AddToRecentFiles _
        :=True, WritePassword:="", ReadOnlyRecommended:=False, EmbedTrueTypeFonts _
        :=False, SaveNativePictureFormat:=False, SaveFormsData:=False, _
        SaveAsAOCELetter:=False
    'Application.Quit

End Sub

Try FileFormat:=wdFormatHTML rather than of FileFormat:= wdFormatFilteredHTML

Beyond stripping tags, saving as Filtered HTML also will reduce images to screen resolution."

From Image quality in "Web Page, Filtered" "... this is by-default for Filtered webpage saves in Word. All mso tags are removed and it's made as small as possible by lowering the DPI to 96"
